Fix docs for lightweight tag creation via API

Closes #17499

See merge request gitlab-org/gitlab-ce!14328

In #37955,we see that the profile had a number of N+1 queries from repeated
access to `cross_reference_not_visible_for?`. This was optimized in previous
versions of GitLab by rendering all notes at once, counting the number of
visible references, and then using that number to check whether a system note
should be fully redacted.

There was also another N+1 query calling `ProjectTeam#member?`, which did not
take advantage of an optimization in prepare_notes_for_rendering that would
preload the maximum access level per project.

Closes #37955

Minor update to address Sean McGivern's comment.

See merge request gitlab-org/gitlab-ce!14311

Explain what a project is instead of what a user can do

When a user selected 'Instance default' as value for the auto devops
settings, this was interpreted as a true value. Now we post an empty
string in this case, meaning we want to set `NULL` in the database.
