Add an editor/contributor section in pages

[wojake]

Can we add a contributor section in all the pages that are editable?

We would need to use some sort of a plugin/API to extract the github repo data.

e.g: https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/

This would be great. I like the popup that Ethereum has with all the contributors to a page.
