Show "Shared runners are disabled for the parent group" alert also on project level

Summary

Follow-up to gitlab-runner#28541 (closed)

The Shared runners are disabled for the parent group tooltip shown there does not appear on the /-/settings/ci_cd page of a project.

Note: In !85923 (merged) we changed the tooltip for an alert, so an alert should be added to the view.

Steps to reproduce

1. Create a hierarchy of parent- and sub-group.
2. Disable shared Runners in the parent group.
3. Create a project in the subgroup.
4. Check its /-/settings/ci_cd page

Example Project

What is the current bug behavior?

This is confusing, because the hint tooltip how to solve this problem is only available on the equivalent page of the project's group.

What is the expected correct behavior?

The same hint tooltip should be shown.

Ideally, we would also link to exactly that group's /-/settings/ci_cd page, where the toggle can be used. #349794 (closed)
