False positive for `unnecessary-ellipsis` on `Protocol` methods

[llucax]

Bug description

`pyright` uses `...` to determine the body of this method is not implemented here. Without using `...`, `pyright` rightfully (IMHO, as is the only way it has to know the user is intentionally omitting the body) complains about a missing return to match the declared return type of the function.

Example:


"""Module docstring."""

from typing import Protocol


# pylint: disable=too-few-public-methods
class P(Protocol):
    """Class docstring"""

    def f(self) -> int:
        """Method docstring"""
        ...


When removing the `...` pylint passes by `pyright` says:

```console
[test] $ pyright t.py 
/tmp/test/t.py
  /tmp/test/t.py:10:20 - error: Function with declared return type "int" must return value on all code paths
    "None" is incompatible with "int" (reportGeneralTypeIssues)
1 error, 0 warnings, 0 informations 

### Configuration
