[Bug] Updated .eslintrc.json is not valid

[HymanZHAN]

• nx version: 10.4.4
• @angular-architects/ddd version: ^1.1.0

TL;DR;

In nx project configured with eslint, the generated eslint config should be put inside the top-level overrides array instead of overwriting the whole .eslintrc.json file

More details:

• What's inside .eslintrc.json after running nx add @angular-architects/ddd and/or nx g @angular-architects/ddd:domain blog:

  {
    "files": ["*.ts", "*.tsx", "*.js", "*.jsx"],
    "rules": {
      "@nrwl/nx/enforce-module-boundaries": [
        "error",
        {
          "enforceBuildableLibDependency": true,
          "allow": [],
          "depConstraints": [
            {
              "sourceTag": "type:app",
              "onlyDependOnLibsWithTags": [
                "type:api",
                "type:feature",
                "type:ui",
                "type:domain-logic",
                "type:util"
              ]
            },
            {
              "sourceTag": "type:api",
              "onlyDependOnLibsWithTags": [
                "type:ui",
                "type:domain-logic",
                "type:util"
              ]
            },
            {
              "sourceTag": "type:feature",
              "onlyDependOnLibsWithTags": [
                "type:ui",
                "type:domain-logic",
                "type:util"
              ]
            },
            {
              "sourceTag": "type:ui",
              "onlyDependOnLibsWithTags": ["type:domain-logic", "type:util"]
            },
            {
              "sourceTag": "type:domain-logic",
              "onlyDependOnLibsWithTags": ["type:util"]
            },
            {
              "sourceTag": "domain:shared",
              "onlyDependOnLibsWithTags": ["domain:shared"]
            },
            {
              "sourceTag": "domain:blog",
              "onlyDependOnLibsWithTags": ["domain:blog", "domain:shared"]
            }
          ]
        }
      ]
    }
  }

• What should the updated .eslintrc.json:

{
  "root": true,
  "ignorePatterns": ["**/*"],
  "plugins": ["@nrwl/nx"],
  "overrides": [
    {
      "files": ["*.ts", "*.tsx", "*.js", "*.jsx"],
      "rules": {
        "@nrwl/nx/enforce-module-boundaries": [
          "error",
          {
            "enforceBuildableLibDependency": true,
            "allow": [],
            "depConstraints": [
              {
                "sourceTag": "type:app",
                "onlyDependOnLibsWithTags": [
                  "type:api",
                  "type:feature",
                  "type:ui",
                  "type:domain-logic",
                  "type:util"
                ]
              },
              {
                "sourceTag": "type:api",
                "onlyDependOnLibsWithTags": [
                  "type:ui",
                  "type:domain-logic",
                  "type:util"
                ]
              },
              {
                "sourceTag": "type:feature",
                "onlyDependOnLibsWithTags": [
                  "type:ui",
                  "type:domain-logic",
                  "type:util"
                ]
              },
              {
                "sourceTag": "type:ui",
                "onlyDependOnLibsWithTags": ["type:domain-logic", "type:util"]
              },
              {
                "sourceTag": "type:domain-logic",
                "onlyDependOnLibsWithTags": ["type:util"]
              },
              {
                "sourceTag": "domain:shared",
                "onlyDependOnLibsWithTags": ["domain:shared"]
              },
              {
                "sourceTag": "domain:blog",
                "onlyDependOnLibsWithTags": ["domain:blog", "domain:shared"]
              }
            ]
          }
        ]
      }
    },
    {
      "files": ["*.ts", "*.tsx"],
      "extends": ["plugin:@nrwl/nx/typescript"],
      "parserOptions": { "project": "./tsconfig.*?.json" },
      "rules": {}
    },
    {
      "files": ["*.js", "*.jsx"],
      "extends": ["plugin:@nrwl/nx/javascript"],
      "rules": {}
    }
  ]
}

Otherwise, nx lint will fail with error:

An unhandled exception occurred: ESLint configuration in apps/desci/.eslintrc.json » ../../.eslintrc.json is invalid:
        - Unexpected top-level property "files".
