Update CI workflows

[ygrishajev]

Currently 2 workflows are happening in parallel on merge to main:

1. tests
2. release
   

which doesn't make much sense as release should depend on tests to be cancelled if ones fail. There are ways to do it a more logical fashion. Some of them are:

• protect master and run test only on feature branches. So that in master it only releases. This one has an issue that tests wouldn't run if a hot-fix is required directly in main
• run release when tests are green. this one is more safe but would double run tests for the same commit if merge is done with a rebase.

It looks like option 2 would be more consistent though.
Some optimisation can be done there by finding/creating a custom action to skip tests if those are already run against head_commit.

Tasks:

• Make sure release does depend on tests
• Skip running tests if already done for current head_commit
