[BUG] Versions conflict due to wrong version constraint in requirements.txt

[nelsyeung]

Describe the bug
Version conflict due to wrong version constraint in requirements.txt.
Looking at PEP440, >=5.*, <=6.* doesn't look right. It should be >=5.0, <7.0.

To Reproduce
Steps to reproduce the behavior:

1. Create your own package your-package that depends on PyYAML 6.0 and pyaml-env 1.2.0

2. Upload the package (I'm using an internal PyPI server)

3. pip download your-package

4. Error:

   ERROR: Cannot install your-package and your-package==1.0.0 because these package versions have conflicting dependencies.
   
   The conflict is caused by:
       your-package 1.0.0 depends on PyYAML<7.0 and >=6.0
       your-package pyaml-env 1.2.0 depends on PyYAML<=6.* and >=5.*
       your-package 2.0.0.dev540 depends on PyYAML<7.0 and >=6.0
       pyaml-env 1.1.5 depends on PyYAML<=6.* and >=5.*

Expected behavior
It shouldn't happen
