fix: remove build on any branches except main and tags

[shanduur]

Description

Build and push only releases and master branch (via cron).

Motivation and Context

Right now every branch that is created in the repo triggers build in the repository. This includes branches created by Renovate. We don't want it - only master (via cron) and releases should be built

I think we need this on the master branch for the edge tag. Its only feature, branches we don't want.

[shanduur]

@AdeAttwood but previously you had '!master' - meaning exclude master from builds.

[shanduur]

Cron job is started on default branch (in this case master) and it will be tagged as edge - no need to explicitly mention it in the workflow.

sorry for the late response. no ci tests for the docker image build? :'(
https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request could be an option, i think.
