Fix 'Forbidden characters' typo

[emmahodcroft]

Description of proposed changes

Fixes a typo, correcting forbidden_chactacters (here) to forbidden_characters

Seems this was introduced 2 years ago - thankfully I hope hasn't caused issues since then. However, I actually use

from augur.parse import forbidden_characters

in a number of my scripts & builds (outside of SC2) - so found this bug when running them for the first time since Jan 2020.

Oh dear, let's hope no one imports forbidden_chactacters now... To be safe, one could add forbidden_chactacters = forbiidden_characters

It was introduced here: 722d52b in March 2020.
