Build of python-rich fails because the version of python-rich is out of date.
As a result, the build of pelican, which depends on python-rich, also fails.
I think this is because the version of pygments has been upgraded and the
problem fixed in the pull request below has occurred.
With this patch, both python-rich and pelican can be built.
gnu: python-rich: Update to 12.4.1.
