Previous MR:
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/29453

**Problem**

Current id contraint does not allow routes with `.` symbol.

* `gitlab-org/gitlab-shell/-/sse/master/CONTRIBUTING` - match
* `gitlab-org/gitlab-shell/-/sse/master/CONTRIBUTING.md` - 404 page

**Solution**

This MR restores the previous value for `id` constraint.

I've added a simple integration test to make sure that routing works
as expected.

Improve error message in DAST CI template

See merge request gitlab-org/gitlab!29388

This change in the template will output an error and a link to the
documentation if the variable is not set.

Migrate ee/ide to Jest

Closes #194288

See merge request gitlab-org/gitlab!28437

- Also migrates to Jest and VTU

Part of this is caused by the removal of "changed"
and "staged" split.

**How come?**

When there was this split, it was acceptable to
see "what's changed compared to staged (or HEAD)".
Now that there is only "staged", when we open we
were unfortunately comparing the "staged" content
against intself...
