[BUG] MonorepoTsProject should lint .projenrc.ts and projenrc/**.ts

[athewsey]

Describe the bug

When generating a MonorepoTsProject, the generated ESLint configuration seems set up to include the projenrc configuration files... But the structure of the eslint task only runs lint in the monorepo packages so does not capture the monorepo-level projen code.

Expected Behavior

Default ESLint configuration for a MonorepoTsProject should also lint .projenrc.ts and projenrc/**.ts files

Current Behavior

I see the created root eslintrc.json seems to explicitly provision for linting the projenrc config files:

{
  "ignorePatterns": [
    "packages/**/*.*",
    "!.projenrc.ts",
    "!projenrc/**/*.ts"
  ],
  ...
  "overrides": [
    {
      "files": [
        ".projenrc.ts"
      ],
      "rules": {
        "@typescript-eslint/no-require-imports": "off",
        "import/no-extraneous-dependencies": "off"
      }
    }
  ]
}

...But the generated tasks.json task just runs eslint in sub-packages via nx - which won't capture the top-level linting:

npx nx run-many --target=eslint --output-style=stream --nx-bail

Reproduction Steps

• npx projen new --from @aws/pdk monorepo-ts
• Edit your .projenrc.ts file with some whitespace error that prettier/eslint should catch
• Run npm run eslint: The projenrc file will not be re-formatted.

Possible Solution

Maybe MonorepoTsProject should add an additional step to the eslint task to run at the root/monorepo level?

I'm tentatively working around it for now with:

monorepo.eslint?.eslintTask.prependExec(
  "eslint --ext .ts,.tsx --fix --no-error-on-unmatched-pattern $@ .projenrc.ts projenrc",
);
