ci: Use cicd-actions setup-bazel-cache and unblock user namespace for linux-sandbox actions

[lurtz]

There is now a release of cicd-actions! Lets make use of that and simplify our code.

cicd-workflows are also being updated: eclipse-score/cicd-workflows#125

setup-bazel-cache

This centralizes bazel caching logic within S-CORE and moves it into a central place of perfection.

unblock linux user namespaces for linux-sandbox

The code in cicd-actions is better tested and should be considered a single source of perfection

Pull request overview

This PR updates the repository’s GitHub Actions CI workflows to use the centralized eclipse-score/cicd-actions implementations for Bazel caching and for unblocking Linux user namespaces required by Bazel’s linux-sandbox, and removes the now-redundant in-repo composite action.

Changes:

• Replace bazel-contrib/setup-bazel@0.19.0 with eclipse-score/cicd-actions/setup-bazel-cache in relevant workflows.
• Replace the local composite action for linux-sandbox user namespaces with eclipse-score/cicd-actions/unblock-user-namespace-for-linux-sandbox.
• Delete the repository’s .github/actions/unblock_user_namespace_for_linux_sandbox composite action.

Is there a reason why only use it for the build workflows and not for the other workflows using bazel?

Ah, never mind, those use the workflow template from cicd workflows.
