chore: pin third-party actions to commit SHAs

[erwan-joly]

Pins every non-GitHub-owned action in this repo to a full-length commit SHA, keeping the version tag as a trailing comment.

A tag is a moving pointer — whoever controls the upstream repo (or compromises that maintainer's account) can repoint it and change what executes here. These steps run with contents: write or cloud credentials in scope, so that matters.

No version changes: each SHA is the exact commit the pinned tag resolved to today. Part of a sweep across the org so sha_pinning_required can be turned on afterwards.

Walkthrough

The .NET release workflow now pins softprops/action-gh-release to a specific commit SHA instead of the mutable v3 tag.

Changes

Release workflow

Layer / File(s)	Summary
Pin the release asset action .github/workflows/dotnet.yml	The Upload Release Asset step references commit efb35369e0ad2afab669f228072c1b0d510eae64 and retains the v3 comment.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to d1b45

The release workflow now uses an immutable action revision, reducing the chance that a mutable tag changes CI behavior. No merge-blocking risk is evident.
