Build images on PRs from community users

[j-zimnowoda]

WHY

Contributors should be able tests their images on their clusters

User Story

AS A OSS contributor

I WANT TO the Build and publish Docker pipeline to be trigger on PR from my fork

SO I can see results of smoke tests and test my changes in runtime

Acceptance criteria

GIVEN OSS contributor WHEN PR to the main branch is opened THEN Build and publish Docker pushes it to Github cache registry (not to dockerhub)

Definition of done

• [ ] Relevant PRs are merged
• [ ] Tested by peer
• [ ] Updated documentation reviewed by peer
• [ ] Short demo video recorded and stored on google drive (if applicable)

Adding to .github/workflows/main.yml file:

on:
  pull_request:
    branches: [main]

could solve this issue but we must ensure that by adding a PR release job is not triggered
