💡 Description

Firefox-ios performance tests currently only output PERFHERDER_DATA to the log.
This PR adds support for generating a perfherder-data JSON artifact (perfherder-data.json) to enable correct ingestion in Treeherder and downstream tooling.

Hi @isabelrios :)
I submitted a PR to solve the issue. From what I can see, jobs for firefox-ios only appear in Treeherder once the code has landed on main. Is there a way to trigger this perftest[0] job (or something equivalent) directly so that I can verify the perfherder JSON artifact before landing?

lgtm, let me know if you have any issues testing the workflow in bitrise for this.

Thanks for helping me out :)
The main goal of this patch is to generate the perfherder-data.json artifact.
I wanted to double check. Would it be possible to try running the bitrise-perf[0] job as well? Earlier on Bitrise I couldn’t find the job, so I’m asking again just in case.

I triggered the Bitrise_performance workflow and I confirm that the json is generated and stored in artifacts: https://app.bitrise.io/build/84f421b3-09ac-4cf3-8275-4470817c51a8?tab=artifacts
