Seems like there's something up with the ecosystem check when it runs on typeshed currently. We've had issues on several PRs where the ecosystem check has produced surprising results that don't make logical sense and can't be reproduced locally:

• [flake8-pyi] Allow simple assignments to None in enum class scopes (PYI026) #11128 (comment)
• [flake8-pyi] Implement PYI062 (duplicate-literal-member) #11269 (comment)
• [pyflakes] Allow forward references in class bases in stub files (F821) #10779 (comment)

No idea what's up here
