Process replace commands in parallel

[JAORMX]

This adds some level of parallelization to the replacer commands for
github actions and containers. Hopefully increasing the processing speed.

Did not see it was stated as WIP, my bad.

this is already an improvement, what's missing to make the PR non-WIP?
I can see as an additional step we might want to use a syncMap to store what has been resolved (many workflows will probably use e.g. actions/checkout), but this will already speed things up.

@jhrozek mostly that I didn't get a chance to test it. If you did test it already I'd be OK with removing the WIP tag.

Will try to test this afternoon when I’m done travelling!

I tested this and it seems to work fine.

I can do this in a subsequent PR.
