With #1467 we know we can run acceptance tests of generated clients - it already works.

Now we need a dedicated GitHub Action workflow that will integrate these tests with the PR review process, like we have normal unit testing automation, or complex test-project testing.

What has to be done:

• workflow that spin up packages/templates/clients/websocket/test/microcks-setup/microcks-podman.yml (something like https://github.com/asyncapi/generator/blob/master/.github/workflows/pr-testing-with-test-project.yml)
• these tests depend on packages/templates/clients/websocket/python/test/temp/snapshotTestResult and packages/templates/clients/websocket/javascript/test/temp/snapshotTestResult, so workflow must assure it has access to generated clients (probably run tests that generate these clients)
• and last but not least - current podman config runs tests, but do not fail - propagate any error - when test fail - so that has to be improved to make sure that the workflow fails whenever tests fail
