⚙️ [Maintenance]: Bring workflows into compliance with the GitHub Actions standard

[Marius Storhaug (MariusStorhaug)]

Brings this repository's inline CI workflows into line with the organization's GitHub Actions coding standard. Runner images are now pinned to specific versions so a runner upgrade is a deliberate, reviewable change, and release runs queue instead of aborting mid-publish.

• Fixes Bring the action into compliance with the GitHub Actions standard #29

Changed: runner images are pinned

No workflow uses a -latest runner any more; every runs-on names a specific image.

• Action-Test.yml — matrix pinned to ubuntu-24.04, windows-2025, macos-15
• Linter.yml — ubuntu-24.04
• Release.yml — ubuntu-24.04

Changed: release runs queue instead of cancelling

Release.yml now sets cancel-in-progress: false, so a release that is publishing queues behind an in-flight run rather than being aborted mid-write. Action-Test.yml and Linter.yml keep cancel-in-progress: true, since cancelling a superseded test or lint run is desirable and is not a publish action.

Technical Details

Validated locally with actionlint (0 issues) on all three workflows; the linter workflow re-checks actionlint in CI.

These workflows are seeded from Template-Action; the same corrections should also land there so regenerated repositories stay compliant (tracked under Process-PSModule#360).

Dependabot update grouping and semver update labels are intentionally out of scope (see MSXOrg/docs#19 and PSModule/Process-PSModule#359).

Pull request overview

Aligns this repository’s inline GitHub Actions workflows with the organization’s GitHub Actions coding standard by pinning runner images to explicit versions and ensuring publish/release workflows queue rather than cancel in-progress runs.

Changes:

• Pinned runs-on across workflows (including the test matrix) to explicit runner images instead of *-latest.
• Updated the release workflow concurrency behavior to cancel-in-progress: false so publishing runs queue safely.
• Kept cancel-in-progress: true for non-publishing workflows (test/lint) to avoid wasting CI on superseded runs.
