A great start! One bug around the repo's template mismatching the .all-contributorsrc badge template, but this is the right direction. Thanks! 🚀

[JoshuaKGoldberg]

This looks great, thanks @5hraddha!

There are some existing inconsistencies in the README.md that make me not super motivated to try to get it all exactly the same. If anybody finds them irksome they can always file an issue. But this PR more than adequately solves for the case of the badge underlines in the template.

[github-actions]

🎉 This is included in version v1.45.0 🎉

The release is available on:

• GitHub releases
• npm package (@latest dist-tag)

Cheers! 📦🚀

[5hraddha]

Thank you! @JoshuaKGoldberg . If there is anything specific you want to resolve from the existing inconsistencies, please feel free to let me know. I can meddle with it sometime after the weekend. Have a great day!

You got it! There were really two things I was thinking of:

1. A couple of the README.md lines were using spaces instead of tabs, I just fixed them in e3eef39 (pushing directly to main)
2. 🛠 Tooling: Lack of indentation in generated README.md all-contributors badge #1041
