fix the ci trigger action (#4805)

* add some more diagnostics

* also print the log after fetching [skip-ci]

* try using the current ref to fetch and checkout the FETCH_HEAD

* add some more options and print the log before checkout

* don't add a progress report when printing to a file [skip-ci]

* add back the progress report but also use -q [skip-ci]

* replace the backticks with tt html tags [skip-ci]

* skip the auto-fetch within the action [skip-ci]
