small difference between raja + camp vs umpire release tarball names

[cyrush]

You may already know this, but just in case it's not on you your radar:

Camp and Raja tarballs include the v in the file name:

https://github.com/LLNL/camp/releases/download/v2025.09.2/camp-v2025.09.2.tar.gz

Umpire tarball lacks the v in the filename:

umpire-2025.09.0.tar.gz

But the tag includes the v
