[bug#54609]

[Philippe SWARTVAGHER]

`git refresh openmpi` seems to be broken for this package:
./pre-inst-env guix refresh openmpi
following redirection to `https://www-lb.open-mpi.org/software/ompi/current/'...
gnu/packages/mpi.scm:194:2: warning: 'generic-html' updater failed to
determine available releases for openmpi

The URL in
```
`((release-monitoring-url
    . "https://www.open-mpi.org/software/ompi/current";)))
```
redirects to a URL containing only the major and minor version, the
patch number has to be found in the content of the page. I don't know if
something has to be fixed and where (in the openmpi package, or is it a
bug from `guix refresh`?).


Regarding the update, I looked very quickly at the changelog
(https://raw.githubusercontent.com/open-mpi/ompi/v4.1.x/NEWS), and
nothing caught my attention regarding the packaging.


Tested by building intel-mpi-benchmarks against this new version of
OpenMPI, succefuly built.


Philippe.
