Query Reporting: Fix query recorder log file path

What does this MR do and why?

For query recording we record queries during rspec runs into an NDJSON log file under rspec/, but this file needs to be named per job, so this MR moves the log file into a new folder (query_recorder/) and names it uniquely according to the CI job environment variables.
