Docs: Make access levels header in Members API doc
Problem to solve
In !32008 (comment 353775045) it was noted that there isn't a header for the Valid access levels
in the Members API documentation. This issue proposes making it a proper header and updating links to access levels in the API to use it.
Further details
Members API docs: https://docs.gitlab.com/ee/api/members.html
We can also update the wording in the API docs to use access level
rather than permissions level
.
Proposal
Add header for valid access levels in the Members API documentation, and update links and wording throughout the API documentation that uses this link.
