Allow AddMethodParameter to match overridden methods

[Anmol202005]

Improves AddMethodParameter so that methodPattern resolution includes overridden methods from interfaces and superclasses.

• Fixes: Allow AddMethodParameter to operate on overridden methods #6287

Checklist

• I've added unit tests to cover both positive and negative cases
• I've read and applied the recipe conventions and best practices
• I've used the IntelliJ IDEA auto-formatter on affected files

@timtebeek kindly review :)

Thanks for the runnable example! I'm off here today, but will try to circle back next week.

I had thought we could clear this up with just changing the expected method pattern instead.

Will likely move into next week before I can get to this; I've got some online trainings to give and a weekend ahead first. 🙏🏻

Thanks a lot for the help here @Anmol202005 ! Found a way to achieve the same without changes to MethodMatcher, to minimize added API surface and potential impact. With that I think we're ok to merge this change.

Appreciate your patience as well; it's not been easy to get to everything, but hope you enjoy some end of year time off there!
