Update version of opinionated-commit-message in workflow

Previously, we used an older version of 
[mristin/opinionated-commit-message] in our
`check_title_and_description` workflow, which lead
to erroneous failing of some PR pipelines. 

This updates our CI workflow to use the newest 
available version of this checker. 

Fixes #442
