Hi! I apologize for the long delay; I have had a very stressful winter and have not had the time or energy to check this repository in a timely manner. I'm trying to catch up now.

Yeah, the documentation has been an ongoing nightmare for me. No matter how carefully I try to read it, I've become essentially completely blinded to small errors like this. Thank you for catching them.

"Forbad" wasn't a typo; that is one of the past tenses of "forbid". However, "forbade" has been overtaking it for a while, so I'm not going to protest.

Never mind. The fixes got merged, and that is what counts. 👍

I was not aware of that. (English is not my first language.) I just checked in the dictionary, and "forbad" is indeed a possible - albeit rarely used - variant of the past tense of "forbid". Seems like I learn something new every day. :)
