Support more granular stack arguments

[deemp]

• Add new inputs to provide separate arguments for stack <command> invocations
• stack-arguments are now passed to stack invocations (closes Specifying resolver in stack-arguments  #26)
• Fix compiler checks in the example action
• Run example action on all platforms
• Convert multi-line inputs to single-line strings

This is looking pretty good, IMO. Just noted a few minor things.

This looks great!

I'm going to pop a link in our team chat for others to take a peek before we commit to it as the new major version's inputs.

Apparently, no one is particularly interested in additional review on this. I plan to merge on Monday, release the new version, and start updating our usages. If you'd like to update the git history before then, please do and let me know. Otherwise, I will probably just Squash merge the whole thing.

Thanks again!

Thank you a lot for curating this PR!

Consolidating this in #36 .
