Have Khoj support Python 3.11 as Pytorch supports it now

- Previously Khoj could only support Python upto 3.10 due to pytorch.
  But lots of folks had python 3.11 installed by default on their machines.

  This required installing python 3.10 and dealing with virtual envs.

  With Torch >= 2.0.1 now able to support python 3.11, at least one
  class of installation troubles for Khoj should drop. See
  https://github.com/pytorch/pytorch/issues/86566 for reference

- Preliminary testing indicates using the new torch 2.x may reduce
  search time by 25% (from 80ms to 60ms on Mac M1)

- Update Docs to not require mentioning python <=3.10 required
- Update Github test workflow to run khoj tests with python 3.11 too

 ## Setup
 These are the general setup instructions for Khoj.
 
-- Make sure [python](https://realpython.com/installing-python/) (version 3.10 or lower) and [pip](https://pip.pypa.io/en/stable/installation/) are installed on your machine
+- Make sure [python](https://realpython.com/installing-python/) and [pip](https://pip.pypa.io/en/stable/installation/) are installed on your machine
 - Check the [Khoj.el Readme](https://github.com/khoj-ai/khoj/tree/master/src/interface/emacs#Setup) to setup Khoj with Emacs<br />
   Its simpler as it can skip the server *install*, *run* and *configure* step below.
 - Check the [Khoj Obsidian Readme](https://github.com/khoj-ai/khoj/tree/master/src/interface/obsidian#Setup) to setup Khoj with Obsidian<br />
