Closes #43603

Adds i18n
Adds test

Fix broken tests

Fixes empty tab state for external CI

- Only if user can manage project,
- When Auto DevOps is not enabled,
- When project configuration is set to implicit

Given the user can soon have multiple config sources for CI, we now store
what type at the time of the pipeline run we chose. This will give us
insight into what triggered the new pipeline so we can display it to the
enduser.

Fix broken test
