Thanks for the PR, @Himanshityagii24, and sorry for the delay on this one...
A few points before being able to move forward on this:
1/
Please do a PR on the action to add Prettier without including all the markdown modifications.
Plus (important) all generic md files like: ADOPTERS.md MAINTAINERS.md.../... must not be modified here but on the main repo. See: https://github.com/microcks/.github

So, all these centralized files must be excluded from the GitHub action.

2/
@mohdaquib171 and @lbroudoux are working on a significant refresh of the hub front end. See: #76
So, this type of action may be of use but may not be the top priority. But always open for improvements, see 1/
