Change how the automatic tests are triggered

[costigt-dev]

Why

The current process triggers a broader test suite when a review is requested which can be wasteful if multiple reviews are requested.

What

There are many alternative ways to do this. One way is to have a section of the PR description template have checkboxes for the test suites you wish to run like so:

• Test group a
• Test group b
• Test group c

some could be default on, others default off and when you want to run more tests, you would manually check them and re-run the workflow or make a commit.

I was about o open a similar issue :)
Another option would be to have tests triggered by special comments in the PR.
