Internal lint issues on Sheriff repo

[tomwhite007]

This is only a suggestion—I'm happy for you to close it if you want. I'm just looking to improve DX.

Expected: As a developer, I would like to see only lint issues affecting my current file.

Actual: For .json and .html files in this repo, I see lint errors that pertain to .ts files. e.g.

.js files also get lint errors for using CommonJS (require(...)) imports.

I propose you let me submit a small PR to convert eslint.config.js in the root to the format of a freshly created Nx repo. This would separate .ts lint rules away from .js, .json and .html files. If you have any special requirements that aren't standard linting rules, you could mention them here.

I'm suggesting this to improve my DX as I work on #165
