revert: ci: use ubuntu-latest for release workflow (#282) (#283)

This reverts commit 4dad26a. This
commit switched to using ubuntu-latest for the release workflow instead
of dealing with firewall issues on the blitzar vm runner. However, the
release workflow now takes over an hour, because it needs to build cuda
from scratch when entering the nix environment instead of taking
advantage of the nix store (cache) on the blitzar vm runner. It will
likely be faster to just squash the firewall issues.
