Upgrade instructor version to resolve the bug caused by removal of "classmethod properties" feature in python3.13

Hi shell_gpt community! I am using shell_gpt with python3.13 recently, and encountered a bug when functions are installed.

Traceback (most recent call last):
  File "/home/xx/Downloads/sgpt_install/venv/bin/sgpt", line 5, in <module>
    from sgpt import cli
  File "/home/xx/Downloads/sgpt_install/venv/lib/python3.13/site-packages/sgpt/__init__.py", line 1, in <module>

TypeError: 'method' object is not subscriptable

This is caused by the removal of "classmethod properties" feature in python3.13.(https://docs.python.org/3.13/library/functions.html#classmethod). Unfortuanetly, this feature is used by the instructor package, and shell_gpt relies on this package in the implementation of function calling. To solve this problem, the instructor community has implemented a classproperty decorator. So upgrade the instructor version can solve the bug. I have noticed that shell_gpt is still using instructor < 1.0.0, maybe we can try to upgrade it?

This a problem on Archlinux now that they've upgraded Python to 3.13.1, shell_gpt is broken, i get the same output as above
