Also:
- remove `blob-report` directory at the start;
- markdown's `report.md` next to package.json;
- use default location in playwright's workflows.

We store shard number in the report metadata event and then sort shard
files by shard number. This guarantees that within each project sharded
events will always go in stable order.
For linux tests without tracing blob-report-1.zip takes 19M, while
unpacked size is 228 MB. That size is counted for GitHub artifact
billing:

We zip individual .jsonl reports so that they still have unique names
and can be easily uploaded into the same artifacts directory without
name collisions.
Project name is used in testId calculation, so patching it in the
reporter is too late. Instead we now save project suffix to the blob
report file and patch all project and test ids as well as project names
in the report merger
Attachments with `path` are stored as `resources/sha1.ext` zip entries
and extracted under `report-dir/tmp` when merging. This way normal
fs.readFile keeps working as before even thought the file path is
different. The clients should rely on `attachment.name` instead of
`attachment.path` when deriving user visible titles in the UI. If this
turns out not to be the case we can reconsider later.
