chore: Add metadata action - step 1

[mvicknr]

Overview

This PR adds the ability for the NR agent team to send agent metadata and binaries to New Relic for use in fleets and other features. This will be triggered normally during a release. but if it fails, it will not fail the release. It can also be run on-demand for backfilling older agent versions, to make corrections, or to re-run the job after a failure.

GH action info: https://github.com/newrelic/agent-metadata-action/blob/main/README.md

Testing

This PR is step 1 that will use aTestAgent agent name instead of NRPythonAgent
This PR needs to be merged to main in order to run the new on-demand workflow
A later PR will add a step in the release and use the real agent name

Also the megalinter step failed to commit I think you can run this locally via:

ruff format && ruff check --fix

You may need to pip install ruff first.
