Loosen python version requirement from `>=3.9,<3.13` to `>=3.9`

[Ravencentric]

Describe the Bug
This project has an upper bound on python version:

coveralls-python/pyproject.toml

Line 34 in ff75b50

python = ">=3.8,<3.13"

This results in a failed installation in other poetry managed projects if they do not define an upper constraint.

To Reproduce

• Create a new project without an upper python version constraint with poetry
• Run poetry add coveralls

Expected Behavior
Remove the upper bound so libraries aren't forced to add an upper constraint to get a successful install

Package Versions

• coveralls 4.0.1

Trace Logs

❯ poetry add coveralls -G dev
Using version ^4.0.1 for coveralls

Updating dependencies
Resolving dependencies... (0.2s)

The current project's supported Python range (>=3.9) is not compatible with some of the required packages Python requirement:
  - coveralls requires Python <3.13,>=3.8, so it will not be satisfied for Python >=3.13

Because no versions of coveralls match >4.0.1,<5.0.0
 and coveralls (4.0.1) requires Python <3.13,>=3.8, coveralls is forbidden.
So, because pocketbase depends on coveralls (^4.0.1), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For coveralls, a possible solution would be to set the `python` property to ">=3.9,<3.13"

Any word on when this metadata update will happen? This is the sole blocker preventing some of my projects from being able to try out Python3.13.

I can open a PR if you'd like!
