github app (or just a template workflow?) to automate collection/pushing of the logs for PRs etc

- if app - it should "subscribe" for events from github to be alerted by github whenever
- PR is submitted
- branch progresses
- probably could even explicitly react on completion of github actions
- if workflow - probably could be something similar (i.e. react on relevant events, didn't check yet for suitable)
- would be configured to provide pushes to a specific repository if app, or the same repo
- well -- do scale it up, should probably

details yet to think through...

the main purpose: to avoid needing some server where cron job is to be ran, and rather just have app enabled or workflow copied into a repository and "be done". DataLad github support (#21) could then help to orchestrate pushing of the entire hierarchy to github (creating new repos as/if needed) and avoiding the need for custom code.
