feat: dyslexic font toggle
Created by: hanna
Summary
Add a toggle in the General settings to enable a dyslexic font.
Purpose
It would be helpful for people with dyslexia (like a friend of mine) if sharkey had an ability to toggle between something like OpenDyslexic and the normal Sharkey font. There is a toggle to use system font, but that doesn't really fully help if the user only has it set per application or per website.
