According to mypy_primer, this change doesn't affect type check results on a corpus of open source code. ✅

It's good to have support for additional enum features.

LGTM. We could also add some similar special casing for this decorator's twin, enum.member -- currently mypy just follows the typeshed stubs, which leads to incorrect results: https://mypy-play.net/?mypy=latest&python=3.12&gist=1f3799c9117af6d8a55552e4018f526d

I'm also fine with that being done as a followup, if you prefer, though!

There are no tests for `@enum.member` used as a decorator, because I can
only decorate classes and functions, which are not supported right now:
https://mypy-play.net/?mypy=latest&python=3.12&gist=449ee8c12eba9f807cfc7832f1ea2c49

```python
import enum

class A(enum.Enum):
    class x: ...

reveal_type(A.x)  # Revealed type is "def () -> __main__.A.x"
```

This issue is separate and rather complex, so I would prefer to solve it
independently.
