Lint Awesome itself

[sindresorhus]

#1394 went stale. Would be nice to finish it at some point. However, awesome-lint could probably be made better first.

Hi @sindresorhus and everyone,
It would be great to revisit this and improve the linting setup for Awesome itself. Enhancing awesome-lint and integrating a robust CI workflow could help maintain quality and consistency across lists.
If anyone wants to collaborate or needs help with this, I’m happy to contribute!
