devops: flakiness dashboard to support new folio report (#6677)

JSON report will change again in https://github.com/microsoft/playwright/pull/6656
This patch modifies azure function to accomodate to the new format.

Note: with the new notion of projects instead of per-test parameters,
we can actually compress dashboard per commit much more efficient. If
the format sticks, we'll follow-up with a `dashboard_compressed_v2.js`.
