Update JS deps, remove knip, misc tweaks (#36499)

- Update all JS deps
- Enable a few more stylelint stylistic rules and fix issues
- Remove knip, it raised another false-positive, this tool is not worth
it when you have to babysit it like that
- Exclude @eslint/json from updating as it requires unreleased eslint 10
([ref](https://github.com/eslint/json/issues/207))
- Update labeler config for new eslint filenames
- Adjust `make help` output
- Add type checking in `stylelint.config.ts`
