feat: remove no-eslintrc and simplify eslint conf (#5809)

- Remove --no-eslintrc to simplify the upgrade path to ESlint >= v9,
  because v9 defaults to aonther configuration file format.
- Simplify the default ESlint configuration removing options that have
  been deprecated, or that are equal to the default ones.

Close #5688
