9829 Use macos-latest runner for shellspec

[bencomp]

What this PR does / why we need it:
It updates the Shellspec workflow to use the newer MacOS runners, since the macos-10.15 are no longer available causing all Shellspec workflow to fail after being queued for a day.

Which issue(s) this PR closes:

Closes #9829

Special notes for your reviewer:
I assume that shellspec works the same on MacOS 11 and up as on MacOS 10.15. I have not tested this.

Suggestions on how to test this:
See that the new jobs pass.

Does this PR introduce a user interface change? If mockups are available, please link/include them here:
No.

Is there a release notes update needed for this change?:
Maybe; if release notes (should) include MacOS compatibility notes, then yes.

@bencomp do you want to try making a no-op edit to a shell script to trigger the shellspec workflow?

From what I see below even something under tests/shell would trigger it? @poikilotherm set this up and would know for sure.

name: "Shellspec"
on:
    push:
        paths:
            - tests/shell/**
            - conf/solr/**
            # add more when more specs are written relying on data
    pull_request:

@pdurbin I could try, but I think only workflows that are on the default branch are run – to prevent cryptominer PRs and other bad stuff. So before this is merged even a no-op change should trigger a job for macos-10.15.

Okay, I did manage to test: https://github.com/bencomp/dataverse/actions/runs/5977459978/job/16217490079

Ha. Thanks. 😄

On my PR at https://github.com/IQSS/dataverse/actions/runs/5968226464/job/16191594100?pr=9787 I saw the same thing you are:

I marked my PR as closing the issue you opened:

• Shellspec jobs and workflows fail because no MacOS (10.15) runner is available #9829

I believe this PR will auto-close when my PR is merged. (Or you can go ahead and close it if you want.)

Thanks! Welcome back! 🎉 ❤️ 🚀

Eh, I will wait and see which is merged first ;)

Perhaps you want to cancel the queued jobs that are waiting for the old runners?
