The weak requirement ~houdini-19+<=20.5 causes a conflict when using the package houdini-20.5.

I thought that by default if a minor/patch version is not specified, then it means "all are ok". But this appears to not be the case.

Environment

• OS Windows 10
• Rez version 2.112.0
• Rez python version 3.9.13

To Reproduce

1. Create two packages, one defining houdini-20.5, the other with the requirement ~houdini-19+<=20.5.
2. Attempt a rez-env

Expected behavior
houdini-20.5 should be accepted by the requirement ~houdini-19+<=20.5.

Actual behavior
