Update GHA reusable workflow ref

[mikelittle]

Pin to altis-dev-tools tip past #1056 (artifact name + module-config input + Packagist bypass + other follow-ups).

Is this intentional to be pinned to a hash? I think this would mean future changes to the workflow would require another change across Altis modules

Yes. That's what was done with the previous (still current) Travis tests. It means when new tests or functionality are introduced that might not apply to old versions, they won't try to run them.
The only exception is the dev-tools module, which references the common module by path so that PRs with changes to the tests, run those changes.
