Feature request: support env vars in schema uri

[giacomorebonato]

Is there any way to support env vars in the URL? Given that it has to be an absolute path, that would give more flexibility.

  "json5.schemas": [
    {
      "fileMatch": [
        "test.json5"
      ],
      "url": "${env:HOME}/my-schema.json"
    },
 ]

It would be nice to leverage the same syntax mentioned in this StackOverflow comment

{
    "java.home": "${env:HOME}/.sdkman/candidates/java/8.0.222.hs-adpt/"
}

or

{
    "url": "${workspaceFolder}/schema.json"
}

Thanks for addressing this!

However, I might not accept #5 as-is since I think it's better to fully implement the sensible syntaxes in VSCode Variable Reference and do proper browser support for vscode.dev before rolling this out, but I'll definitely look into this.

Fair point. Thanks!
