Updated Khan Academy colors to new colors

Summary: The KaTex renderer used to use old Khan Academy colors when displaying colored text. The configuration is now updated to have the new colors.

Test Plan:
- verified that colored text now uses the new colors in a browser
- running commands such as `\blueA{blueA}` will style the text in the blueA color from the configuration
