fixed feature headers in README's

[CeleritasCelery]

Updated the feature header in README's to match the Spacemacs style guide as requested in #9476.

Note that we have a spurious error in circleci

File "/root/project/layers/+source-control/version-control/README.org" has multiply "Features:" lists in the top level "Description" headline

which is incorrect. It looks like it is flagging this file because it has the word "feature" in a table. Hopefully @JAremko can fix that.

@CeleritasCelery

File "/root/project/layers/+source-control/version-control/README.org" has multiply "Features:" lists in the top level "Description" headline

That's because you need extra white spaces before git-gutter, or git-gutter+ try this:

** Features:
- highlights uncommitted changes in the fringe or margin with [[https://github.com/dgutov/diff-hl][diff-hl]],
  git-gutter, or git-gutter+
- adds vcs transient-state ~SPC g.~ to allow quick navigation and modification of buffer hunks.

Without them there will be two lists (accordingly to org-mode parser 😏 )

Btw. What's up with your email/account? Can you fix it? 🤔

@JAremko What do you mean? Because I am using different credentials for commits then I am for the pull request? Is that a problem? I went ahead and rebased/reauthored my commits anyway.

Yeah. We want your name in contributors 😉

I always wondered why I never got the "Contributor" tag. I assumed it was because all my commits were cherry-picked. Anyways, looks like the build is clean and all the documentation issues related to it are fixed.

Thank you ! 👍 Cherry-picked into develop branch, you can safely delete your branch.
