Fixes #13030
This is pretty simple, currently pip prefers pinned requirements, e.g.
requests==2.32.2
, when resolving so as to follow a path through the requirement graph that does not increase the number of possibilities.However, the current code considers a requirement like
requests==2.*
to be pinned, which it is not. This fixes that.
