[Feature Request]: Fix All code action for suggestCanonicalClasses

[juliusmarminge]

Currently, the suggestCanonicalClasses have a quick fix, but you have to do it one by one. Would be neat if we could have a code action that fixes them all, that we could also run on save:

  "editor.codeActionsOnSave": {
    "source.fixAll.tailwind": "explicit"
  },
