• I am on the latest Pendulum version.
• I have searched the issues of this repo and believe that this is not a duplicate.

• OS version and name: macOS 13.6
• Pendulum version: 3.0.0b1

Issue

The version is currently constrained to >=5.9.0,<6.0.0, a directly translation of the original Poetry caret constraint ^5.9.0. The upper bound should probably be removed.

Similarly, the upper bound on backports.zoneinfo could be removed, as well as the python_version >= "3.7" markers now that support for Python 3.7 was removed.
