$value requires that the key parameter be called 'key' in order to bind the value at runtime

Assemblies affected

Microsoft.AspNetCore.OData 7.0.1

Reproduce steps

add the following code to the bottom of the movies controller in samples\AspNetCoreODataSample.Web\

public string GetTitle(int SomeKindOfKey)
{
    var thing = _context.Movies.FirstOrDefault(c => c.ID == SomeKindOfKey);
    return thing?.Title;
}

Run the project, navigate to http://localhost:5913/efcore/Movies(1)/Title/$value

Expected result

should return "Conan" in raw form without the quotes

Actual result

null reference because SomeKindOfKey was 0 instead of 1

Additional detail

Its weird that this doesn't have any trouble until adding $value on the end, changing the parameter name to key causes everything to work, but what do I do with a composite key, I cant name both parameters key.
