Does this close any open issues?

Closes #6135

Screenshots

data fetched from a real GitLab instance:

The processing of the data after the collection is tested with the trigger_job_test.go

I will merge it after solving the issue #5920

LGTM, to be merged after v0.21-beta1 released

When running this SQL, table _raw_gitlab_api_trigger_job doesn't exist.

@Marco-De-Stefani I encounter a problem when running the latest main branch and the log is

time="2024-01-29 19:39:08" level=info msg=" [pipeline service] [pipeline #8] [task #59] finished step: 17 / 35"

And I think SQL in function GetAllPipelinesIterator is the root cause. Please check the codes.
I have created an issue #6892, hope it will be fixed.
