Remove /workflow/README.md and redirect to /ee index
Problem to solve
https://docs.gitlab.com/ee/workflow/ now has deprecation details about why the content was removed/moved. In order to provide a good experience for those who may still land on the page via search engines, and because there is no single optimal place to redirect to, we'll leave the page up for a while before removing and redirecting it.
Proposal
Hold off until issue due date.
Remove deprecated page and redirect it to GitLab product docs index.
Who can address the issue
GitLab technical writer
