Add
[`stylelint-value-no-unknown-custom-properties`](https://github.com/csstools/stylelint-value-no-unknown-custom-properties)
which lints for undefined CSS variables. No current violations.
To make it work properly with editor integrations, I had to convert the
config to JS to be able to pass absolute paths to the plugin, but this
is a needed change anyways.
Updated to actions/labeler@v5
Updated labeler config accordingly, also improved the config and added
more labels.

Alternative to https://github.com/go-gitea/gitea/pull/27439. Removes a
few spammy labels, and disables `sync-labels` which make it never remove
labels (which is default behaviour).
