Support Nuxt 3 with reference to https://github.com/wattanx/style-resources-module.
(If you would prefer to make the PR a little smaller in size, please let me know.)

I think Same Repositories, same package name is better.

In this case, same package + same repository is more than fine 👍

LGTM besides a few nits 👍

Thank you for your review ❤️
Added description to use nuxtjs/style-resources@^1.
Is it OK to create a v1 branch?
(If OK, I would like you to make it as I do not have the authorization to do so 🙏 .)

Not sure what this Travis CI integration is doing. Going to merge as it seems good to go, can make any fixes outside of this PR.
