The credentials are created with
`az ad sp create-for-rbac --name "playwright-github-actions" --role
"Storage Blob Data Contributor" --scopes /subscriptions/<subscription
id>/resourceGroups/<resource
group>/providers/Microsoft.Storage/storageAccounts/<storage account>`
We cannot use `azure/login@v1` for login as it does not see to properly
propagate credentials to `azcopy` in the next step (there are some
reports about keyring problems on linux based actions).
Also:
- remove `blob-report` directory at the start;
- markdown's `report.md` next to package.json;
- use default location in playwright's workflows.
References #24451.
Since all resources are uploaded in the separate workflow anyway there
is not much point in passing the options and uploading blob reports as a
separate step.
* Fix report downloading from Azure (reports are now zipped)
* Extracted upload logic into an action
* Extracted PR number file generation into its own job
Fixes

This reverts commit a1cdae6bff.
The problem with this approach is that each job overwrites the zip
artifact whereas previously it was merging all reports in the same
directory. We are going to zip .jsonl files instead.
