did it with a little script

I still need to make it handle links with /user/ like:

Hello, thanks for your contribution!
I apologize for the time to answer you, I just got a few questions. While it might be a nice addition to the repo, it would need to be run at least once a week or something similar to keep it accurate. And the ´/user´ problem should be dealt with. What are your thoughts @naveen521kk?
Sincerely,
Lucas

Hmm, no particular comments about this one. I do agree that it should be run at least once in a while so that it's updated.

Also make sure not to break manim-website-api while adding this.
