Automate tasks on new PaSh releases

[dkarnikis]

Automate the following tasks when a new PaSh version is released:

• [x] Update docker containers
• [ ] Add a new github release
• [ ] Update packages for distros (currently, only Arch has a package)
• [x] Update the official website (for the moment, this has to be done manually)

I am quite positive, that the first three tasks can be automated using github actions.

Great issue—I agree about the first three, and I can likely take care of automating most of the last task.

Docker containers are updated automatically when a new update is merged with main branch regardless of the current PaSh version (Fedora 35 docker support is currently broken, waiting for a docker update to fix the issue).

The next step would be to automatically generate a new github release when PaSh version gets updated

I think that all of those are currently automated!
