ci lint page not available on new projects (under gitlab.com project namespace)
### Summary
Pipelines intro page doesn't include a CI Lint button, documentation it links to suggests going to `/ci/lint` in the project scope (instead of `/-/ci/lint`)
Note: since it's moved from `gitlab.com/ci/lint`, why not have a selector[^1] there if you want it project-scoped now, for legacy/convenience?
[^1]: of your projects, to their respective `/-/ci/lint` page
