* Add optional refresh parameter
Renamed several `RefreshDescriptors` methods to `RefreshDescriptorsAsync` to reflect their asynchronous nature consistently. Added an optional refresh parameter in the `ListActivityDescriptorsRequest` class and updated related endpoints to handle this parameter, triggering a registry refresh if necessary.
* Update version to 3.2.0-rc5 in GitHub Actions
Modified the `packages.yml` workflow to change the version from `3.2.0-rc4` to `3.2.0-rc5` for non-tagged releases. This ensures version consistency with the new release candidate.
