Current behavior

After updating my repository to nx v15, the nx-distributed-task action throws the following error for test, lint, e2e targets (seems to work for build):

TypeError: Cannot read properties of undefined (reading 'some')
    at exports.shouldRunWithDeps (/home/runner/work/_actions/e-square-io/nx-distributed-task/v2/main.js:29:805582)

My nx.json was updated by the migration scripts and the targetDefaults property now looks like this:

  "targetDefaults": {
    "build": {
      "dependsOn": ["^build"],
      "inputs": ["production", "^production"]
    },
    "e2e": {
      "inputs": ["default", "^production"]
    },
    "test": {
      "inputs": ["default", "^production", "{workspaceRoot}/jest.preset.js"]
    },
    "lint": {
      "inputs": ["default", "{workspaceRoot}/.eslintrc.json"]
    }
  },

Expected behavior

The action should work like for nx v14 repositories

Minimal reproduction of the problem with instructions

Update a nx v14 repository to v15

Environment

- Nx version: 15.0.13 
- Node version: 14
