Stricter Python versions

[suncerock]

The current restriction in environment.yml for python is - python>=3.8.0, <4.0.0. However, the default numba version 0.59.1 does not support python 3.13 and gives the following error:
RuntimeError: Cannot install on Python version 3.13.0; only versions >=3.9,<3.13 are supported.

Changing the python dependency to
- python>=3.8.0, <3.13.0
and removing the version restriction for synctoolbox
- synctoolbox
solves the problem for me.
