Fix Broken cpp_build by Pinning Openmpi Build Ver (24.08)

[nv-rliu]

Addresses #4474

Currently openmpi=5.0.3-hfd7b305_105 is blocking our CI cpp_build job. This PR pins that version to unblock that.

Most likely introduced by this PR: conda-forge/openmpi-feedstock#158

LGTM, please link the issue to remove the temporary pinning to this PR when you get a chance.

This needs to target 24.06 too. Builds for 24.06 are currently blocked which is delaying the release.

@nv-rliu I think this PR can be closed, as all these changes ended up in 24.06 and then forward-merged into 24.08 in #4489.

You can see the pin made it to branch-24.08 here:

cugraph/dependencies.yaml

Line 369 in 52712cd

- openmpi<5.0.3 # Required for building cpp-mgtests (multi-GPU tests)

I've opened #4496 to test removing that pin.

Ah, thanks for the reminder @jameslamb

This was opened when I wasn't sure which branch we were merging changes into. Closing now!
