1. Update `stylelint` dependencies
- As of stylelint v15, we do not need `stylelint-config-prettier`
anymore:
https://github.com/prettier/stylelint-config-prettier/releases/tag/v9.0.5
2. Switch to `stylelint-config-standard`:
`stylelint-prettier/recommended` has not been updated for a long time
and still needs the old `stylelint-config-prettier`
3. Handle new `stylelint` issues
They weren't applied to wrong classnames, this PR fixes that and also
expands the weather util tests
