Update Stylelint Config to `stylelint.config.mjs`

[coliff]

Not urgent or anything but the standard Stylelint config is now stylelint.config.mjs.

Stylelint still supports .stylelintrc.json for now (which Bootstrap currently uses) but support for that may be removed in a future update.

REF: https://stylelint.io/user-guide/configure

Makes sense for Bootstrap to update the config.

Hi Christian, Thanks for bringing this to our attention. Updating the Stylelint config to stylelint.config.mjs makes sense to ensure we are aligned with the latest standards and prepared for future updates. I will look into making this change for the Bootstrap repository. Best regards, Liv Bell

Hi Christian, I agree that updating the Stylelint config to stylelint.config.mjs is a good move to stay aligned with current standards. Since Liv Bell has offered to look into making this change for the Bootstrap repository, I will wait for further updates on their progress.
