Split the suggest fix workflow and update docs

[HollowMan6]

Since many people just copy and paste the workflow into their repo, and they only want to do the fixes in the PR review.

So here we make the workflow more reusable by splitting the suggest fix workflow into 2, one focuses on PR code review, another focuses on direct commits PR raising.
