[VIDEO-3086] Configure gst-plugins-rs source, ref

[btgoodwin]

Updated the github action to add recipes_remotes and recipes_commits into the configuration file, pointing gst-plugins-rs at our repository. The target including the following two changes is 0.12.9-lldc.1, here.

1. [VIDEO-3085] Add extra event forwarding to intersink element gst-plugins-rs#2
2. [VIDEO-3092] (Resurrected) Backport awss3sink softseek from upstream PR gst-plugins-rs#5

I'm stumped. Earlier I let it run with a different existing tag and it was fine. Now it's not with the new tag. Their readme says "branch"...which won't be great; the variable is called commits after all.

Look'n good. It made it past the fetch step @jawilson. Please let me know if this is implemented how you would have preferred. I used a pair of input variables to tie this back. The one for the ref can either be the lldc/<branch name> or a tag that's unique to our repository, as is currently set in this PR.

We'll need to also update the config-hash calculation. I'd suggest something simple like:

config_hash=$(echo "${CERBERO_ARGS}${{ inputs.config }}${GST_PLUGINS_RS_SOURCE}${GST_PLUGINS_RS_REF}" | sha256sum | cut -d' ' -f1)

LGTM assuming the build passes.

@jawilson Well, it's through the wickets but I can't merge to the branch because it's protected. I assume you have permission?

Got a little carried away with the branch protection rulesets. I couldn't merge either. Updated and good to merge now.
