Pending Slicer PRs - MultiVolume hash updates

There are two trivial PRs that update hashes for the MultiVolume* components.

Can someone please merge, or let me know what is the concern?

Unfortunately, I lost my svn password stored in the settings in the process of system recovery, and do not know how to restore it, so I cannot commit to svn myself.

I’ll take care of these.

Committed in r27271 and r27272.


Thank you @lassoan for taking care of this!
