Trying to access an object attribute on the class itself doesn't raise errors

[tusharsadhwani]

To Reproduce

class SimpleClass:
    def __init__(self) -> None:
        self.a = "test"

print(SimpleClass.a)

Expected Behavior

I was expecting SimpleClass.a to be caught as an error.

Pyright does catch it:

asd.py
  asd.py:5:19 - error: Cannot access member "a" for type "Type[SimpleClass]"
    Member "a" is unknown (reportGeneralTypeIssues)

Actual Behavior

No issues found.

Your Environment

• Mypy version used: 1.3.0
• Mypy command-line flags: --strict
• Mypy configuration options from mypy.ini (and other config files): N/A
• Python version used: 3.11
