Heads-up: updating python-pynamodb to 6.0.0 in Rawhide

[Ben Beasley]

In one week, 2024-01-21, or slightly later, I will update 
python-pynamodb to 6.0.0 in Rawhide[1]. This is a major version update 
with breaking changes[2]; however, there should be no impact to other 
Fedora packagers since python-pynamodb is currently a leaf package.
