Using RequireAuthorization results in an ambiguous method compilation error

[davidfowl]

Describe the bug

Trying to require authorization on an endpoint route without passing authorize data or a policy name results in a compilation error.

To Reproduce

app.UseRouting(routes =>
{
	routes.MapApplication();

	routes.MapGet("/", context =>
	{
		return Task.CompletedTask;
	})
	.RequireAuthorization();
});

Expected behavior

It shouldn't result in a compilation error.
