Staticman fails to create pull request when making comments

[hendrixjoseph]

Staticman fails to create a pull request when a comment is submitted. A new branch with the comment file is created, however.

I've upgraded from Staticman v2 to Staticman v3 (as a github app) according to Staticman issue #243. This issue happened with both v2 and v3 - see issue #6215.

Theories:

• Staticman no longer has pull request permission due to the large number of spam PRs
• Apps in general no longer have pull request permission due to the large number of spam PRs (verified as false with issue [ImgBot] Optimize images #6217 )
• Something else I'm doing wrong
• Something else wrong with Staticman
