Github actions ephemeral registration option.

Adding in github's new ephhemeral flag when running the config.sh could be of benefit.

For your consideration.

Thanks!

We support this functionality with cml-runner --single since #393, by making use of the undocumented --once option, which is fully somewhat equivalent to the newly introduced Runner.Listener configure --ephemeral option from actions/runner#660.

cml/src/drivers/github.js

Line 239 in 2e9a21d

return spawn(resolve(workdir, 'run.sh') + (single ? ' --once' : ''), {

Even if they're fully equivalent, the latter is going to be deleted on October 2021 and we should use the new option instead.

Shouldn't this be a more robust option when handling any errors?

I didn't look too deep but their change (I hope)/a quick glance at the changes, it is more than a simple name swap, pretty sure it passes the flag when first reaching out to GitHub so that the GitHub side knows it's only good for one job?

The GitHub Actions service will then automatically de-register the runner after it has processed one job.
