Update stylelint config (#33419)

- Inherit stylelint config from
[`stylelint-config-recommended`](https://github.com/stylelint/stylelint-config-recommended),
removed all stylelint core rule options that were either already in
their config or disabled.
- `no-descending-specificity` diverges from their config, seems to much
work currently.
- Tweaked a few rules.
- Added
[`stylelint-define-config`](https://github.com/stylelint-types/stylelint-define-config)
so that typescript can validate the config.
