This updates the developer documentation to reflect the fact that we
stopped using CI_PRE_CLONE_SCRIPT to make the gitlab-org/gitlab CI Git
fetch workload manageable.

This changes the workhorse_use_sidechannel feature flag to be on by
default. This is a performance improvement for Git fetch traffic, see
https://gitlab.com/groups/gitlab-com/gl-infra/-/epics/463.

For self-managed installations that have configured a gRPC proxy to
sit between Workhorse and Gitaly, this will break things. The solution
for that is to remove the proxy or change it to a TCP proxy. Having a
proxy between Workhorse and Gitaly is not a recommended configuration
but we cannot rule out that someone chose to do this. Also see
https://gitlab.com/gitlab-com/gl-infra/scalability/-/issues/1301.

This commit intentionally leaves the feature flag around so that in
case someone runs into this problem, they have a temporary workaround
(disabling the feature flag) besides the real solution (not using a
gRPC proxy).

DevOps Report (singular) actually refers to 2 features. That has caused
confusion. This changes it to be DevOps Reports (plural) in the UI, to
indicate it is a category. This aligns the app with the marketing
content, which already uses the plural version.

This also fixes some references to DevOps Report that should be
references to DevOps Adoption or DevOps Score.

Refactor labels selector in board scope

See merge request gitlab-org/gitlab!71983

Some time ago we made all specs default to preventing cross database
modification. Thus the `prevent_cross_database_modification` tag was
unecessary. This meant slightly re-organising the tests and removing 1
redundant test and re-writing one test slightly since it wasn't covered
elsewhere.

Excludes project namespaces in autocomplete routes finder.
