[New-bugs-announce] [issue45519] Minor docstring improvement in __contains__

[Ivan Savov]

New submission from Ivan Savov <ivan.savov at gmail.com>:

Currently,

```
>>> help(list.__contains__)
```
returns
```
Help on wrapper_descriptor:
__contains__(self, key, /)
    Return key in self.
```

Which is a conceptual circular reference,
since `in` is implemented by `__contains__`.

Changing the help string to

"Return True if key in self."

would fix this.
