**Investigation:**
- According to
[here](https://github.com/microsoft/playwright/actions/runs/8351676198),
the job got cancelled, because someone force-pushed and another commit
took priority.
- We have `if: always()` for uploading the blobs, even if they are
cancelled. We expect, that the task before (`npx playwright test`)
finished writing the blob, but it didn't - cancelled in between. We
still upload - a broken one.
- We download the broken zip and it breaks from there on.
Proposed change: Instead of uploading always, upload if it did not get
cancelled.
Quoting from the GitHub Actions docs about `always()`:
> Warning: Avoid using always for any task that could suffer from a
critical failure, for example: getting sources, otherwise the workflow
may hang until it times out. If you want to run a job or step regardless
of its success or failure, use the recommended alternative: if: `${{
!cancelled() }}`
This is phase 1/2 where it changes our code to use this new condition.
The actual roll-out happens once it works for us.

* Fix report downloading from Azure (reports are now zipped)
* Extracted upload logic into an action
* Extracted PR number file generation into its own job
* Moved report merging and publishing logic into create_test_report.yml
shared between all workflows
* Merged reports are now published for try jobs on pull requests too. In
order to achieve that the logic had to be extracted into a separate
workflow triggered by
[workflow_run](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#workflow_run),
this way it can access secrets even if the original workflow was not
able to.
* The blob report data flow is different depending on whether the
workflow is triggered by a pull request or a push:
- For `pull_request` the workflow doesn't have access to the secrets it
uploads the blob report to the GitHub
artifact storage. Later on the merge workflow uploads that blob report
to Azure blob storage.
- Workflows triggered by `push` event can read secrets. They upload blob
report directly to Azure blob storage
and the merge workflow downloads the report from there rather than from
GitHub artifacts.
