cf14481f - Semantic syntax errors: better error message for global vs parameter (#24902)

Semantic syntax errors: better error message for global vs parameter (#24902) ## Summary This is an attempt to improve the error message for something like ```py a = 1 def f(a): global a ``` I realize that the previous wording ("name 'a' is parameter and global") is used by CPython itself, but unless we are trying to be consistent with CPython, I think we can improve upon this? The previous version seemed a bit cryptic to me when I first saw it. ## Test Plan Updated snapshot tests
