github actions runs the comment validation for every comment which in
turn downloads and runs a new container on every execution.
This is wasting many resources and also there is a big delay when
starting a test so need to think for a different design and for now will
disable GH actions.
An addition to this people are receiving an email for each posted
comment that fails the validation
