Discussion: Module testing GHA path updates

[sjspielman]

Two items I've noticed about triggers for module testing GHAs, using this for example:

OpenScPCA-analysis/.github/workflows/run_doublet-detection.yml

Lines 25 to 27 in c6a0a24

	paths:
	- analyses/doublet-detection/**
	- .github/workflows/run_doublet-detection.yml

1. I wondered if we want to update path to exclude Dockerfile? The reason for this is if a Dockerfile has been updated, then the environment is not up-to-date for the analysis to run successfully. That said, this only is true if the GHA is actually using the Docker image. So, perhaps this something we'd do internally: When we update GHAs to pull Docker images, we'd also update it to exclude the Dockerfile path as a trigger. (GHA path docs)
2. At once point, I had added .github/workflows/run_doublet-detection.yml into the paths field. We might consider doing this more generally and/or adding it to the template module testing GHA

Let's do this, yes!

Note that we will need to revert the change noted in #746 (comment)

As for the Docker question, if changes are only in the Dockerfile/.dockerignore, then there is not much point in rerunning the workflow whether or not the action is using Docker, so we may as well do that too.
