chore: 🔧 Update Python version constraints in configuration files

* Adjusted `requires-python` in `pyproject.toml` to `>=3.12,<3.13`
* Modified `envlist` in `tox.ini` to remove Python 3.13
* Updated `python-versions` in `poetry.lock` to reflect the new constraints
* coloredlogs does not support py3.13, yet, see https://github.com/xolox/python-coloredlogs/issues/119
