gitlab: remove project ID lookup for CI Bridge jobs

The project ID for Bridge jobs (downstream pipeline) were being retrieved
from the WebURL text butchering plus one additional API request for looking
up the project based on the name.

Few releases ago GitLab started to expose the project ID in the pipeline
object for such jobs. Now, it's possible to get it without any additional
pipeline request.
