ci: get docker merge passing; fixes #283

[rockett-m]

Changed docker merge stage to run on pull-request in addition to merge to see if it will pass or fail before a merge takes place. .github/workflows/docker-push.yml
Although it is for testing, it might be valuable to keep this to avoid future issues

Edited the.dockerignore and Dockerfile so that scripts/activate-venv.sh is found
Error:

...
251.1 scripts/install-build-tools.sh: line 87: /scripts/activate-venv.sh: No such file or directory

Added '.' to scripts/install-build-tools.sh sourcing the venv instead of 'source' due to Michael's point about sh not being able to run source.

@HalosGhost and/or @maurermi would you be able to review this? Thanks

[maurermi]

UT-ACK. This looks correct, will give it a test shortly, but I have high confidence. Thanks for patching this quickly.

feedback updated

I will remove the additional docker-merge run on pull-request when we are good on the changes pre-merge

docker-build.sh runs successfully on ubuntu 22.04 disk image with these changes fyi

Just ran and 8/8 checks passed. I had the docker merge stage included to see if it would pass.

I have now removed just the docker-merge on pull-request and re-pushed the commit. Should be good to go now

in a seemingly related issue act is now broken testing against trunk, so I cannot reproduce this working locally; however, I saw the passing CI test, and I see that the push workflow finished correctly on your fork. I'll merge this in-hopes that it solves the immediate CI/CD problem, but a fix to generally narrow the gap between pull and merge docker workflows, ideally also fixing act for testing will be much appreciated.
