[BUG] `client.beta.files.upload` `PathLike` error

[tl-hbk]

Based on the function signatures, client.beta.files.upload should support a PathLike as the second element in the tuple.

FileContent = Union[IO[bytes], bytes, PathLike[str]]

But if I pass something like file=("foo.txt", Path("foo.txt"), "text/plain") to upload it fails because in to_httpx_files -> _transform_file the first if block catches the tuple so the second if in the function that handles reading in the PathLike contents for tuples is unreachable.
