[OMPI devel] Open MPI v5.0.x branch created

[Geoffrey Paulsen via devel]

Open MPI developers,

  We've created the Open MPI v5.0.x branch today, and are receiving bugfixes. Please cherry-pick any master PRs to v5.0.x once they've been merged to master.

  We're targeting an aggressive but achievable release date of May 15th.

  If you're in charge of your organization's CI tests, please enable for v5.0.x PRs.  It may be a few days until all of our CI is enabled on v5.0.x.

  Thanks everyone for your continued commitment to Open MPI's success.

  Josh Ladd, Austen Lauria, and Geoff Paulsen - v5.0 RMs
