remove error contact Ralph message

Please see #13450 for more info that should be added to this doc. The PRRTE docs have already been updated - might be worth comparing to those docs to ensure we are in sync.

These are good fixes for correctness. @rhc54's right that we should probably also merge in the changes from https://github.com/open-mpi/ompi/pull/13450/files for a few more SGE fixes.

We might also want to compare to openpmix/prrte#2300 to see if Ralph made any other systemtic changes that would either be worth pulling over here or somehow just referring to those docs from ours. If we point to the PRTE docs, is there a way we can embed those in our docs? I ask so that users who are in disconnected-from-the-internet environments can still have a full copy of the docs locally in their Open MPI install.

i think we should include links to the related prrte docs. I don't know about embedding. sounds like a chatgpt question concerning sphinx.
