Remove tests with invalid syntax (Python 3.14)

[sharkdp]

The use of named expressions and await expressions results in syntax errors on Python 3.14 (see below). This PR therefore suggests to remove two tests from conformance/tests/qualifiers_annotated.py that were making use of this now-invalid syntax.

                                             ^^^^^^
SyntaxError: named expression cannot be used within an annotation



>>> async def func3() -> None:

    Good10: Annotated[str, await func3()]
                           ^^^^^^^^^^^^^
SyntaxError: await expression cannot be used within an annotation

This is a drive-by fix. The latest version of pyrefly does not seem to support --no-summary anymore. Let me know if this should be removed or pulled out into a second PR.

This looks good to me.
