I tried testing the changes locally but it failed with the following error:

Error: Could not find "./lib/rules/custom-property-no-duplicate-declaration/custom-property-no-duplicate-declaration". Do you need the "configBasedir" or "--config-basedir" option?

Looking into it, looks stylelint 14+ only works for css out of the box and some additional changes to stylelint.config.js are needed according to the upgrade guide: https://stylelint.io/migration-guide/to-14

Looks like this was an issue caused by missing files when packing. When adding those files, new config now runs successfully.

However there is a deprecated rule would need to be removed.
