Improve Installation for Blind / Vision Impaired Users

[C-Loftus]

Should be made easier for those with no or low vision. Many steps to install talon, knausj, nvda, remove character / word dictation. All these settings add significant user friction. Not entirely clear what the best way to do this though since knausj is a git repo and thus should really be cloned. Thus the user needs git and likely another step. Difficult to say what is necessary and what can be automated in the background when installing

Some of this is blocked until Talon 0.5 where there will hopefully be some UX improvements for new users. Wait until this is released to tackle this
