Difficultly maintaining pinned github actions

In one of the repos I contribute to (https://github.com/open-telemetry/weaver) we use pinned github actions and then renovate to maintain them.

I was able to get the pin setting working as described [here](https://axodotdev.github.io/cargo-dist/book/ci/customizing.html#pinned-actions-commits. However my issue arose when renovate started proposing updates as dist-workspace.yml was not being updated. After multiple attempts I can renovate to detect the dependencies in dist-workspace.yml but determine the new digest always fails. It appears not to be supported.

I was wondering could we get a new setting preserve `github-action-version` which if true, sources the version for the actions from the existing releases.yml file rather than dist-workspace.yml. This would be the nicest solution and our recommendation/guidance would become, set it to true if you are using a dependency management tool such as renovate.

Start with the pinned-actions guidance linked in the issue, then compare how dist-workspace.yml and releases.yml currently represent GitHub Action versions. Determine where a preserve github-action-version setting belongs and how it should interact with Renovate. Done means the setting reliably sources action versions from releases.yml and the recommendation is documented.
