fix bittensor not installing under Python 3.13

Bug

bittensor is not installable under python 3.13

Description of the Change

This is very similar to #1967 , as change is quite simple - loosen up dependency version specifiers to allow for a wider range of environments and easier development with current versions.

Currently, under python 3.13 following error pops up:

ERROR: Ignored the following yanked versions: 1.0.0, 1.0.1, 1.0.2
ERROR: Ignored the following versions that require a different python version: 1.21.2 Requires-Python >=3.7,<3.11; 1.21.3 Requires-Python >=3.7,<3.11; 1.21.4 Requires-Python >=3.7,<3.11; 1.21.5 Requires-Python >=3.7,<3.11; 1.21.6 Requires-Python >=3.7,<3.11; 1.26.0 Requires-Python <3.13,>=3.9; 1.26.0b1 Requires-Python <3.13,>=3.9; 1.26.0rc1 Requires-Python <3.13,>=3.9; 1.26.1 Requires-Python <3.13,>=3.9; 2.0.0 Requires-Python >=3.7,<3.12; 2.1.0 Requires-Python >=3.7,<3.12; 2.1.1 Requires-Python >=3.7,<3.12; 2.1.2 Requires-Python >=3.7,<3.13; 2.2.0 Requires-Python <3.13,>=3.9

This PR fixes that.

Alternate Designs

none sensible I could come up with

Possible Drawbacks

same as #1967 ; tl;dr outweighed by benefits

Verification Process

Manual installation under python 3.13

• regression tested with bittensor unittests under all supported python versions i.e. excluding Python 3.13. This is just so installation passes.

Release Notes

• make bittensor package installable under Python 3.13 . This doesn't mean Python 3.13 is already officially supported, but it is a step towards that goal.

LGTM. Just update the branch, and I'll merge it in.
