By shaving off requirements in
#472
#473
#474

We've dropped the requirements list from 61 down to 50, while also removing the Linux additional dependencies: depends_on glib, libsoup, webkitgtk.

Namely we've removed:

• python-levenshtein
• gitdb (no need to install GitPython for the brew version)
• pluggy
• pywry
• pip (no need to double-install pip)
• fuzzywuzzy
• pytest
• iniconfig
• rapidfuzz
• setproctitle
• Levenshtein

Failure caused by the build process not including the bittensor_cli/src/bittensor/templates directory in the build. Resolved by adding MANIFEST.in in #479 and released as 9.5.1.
