Fix S2094 FP: Allow empty queries

[fraserkyle]

Description

It is not an uncommon pattern to have Querys with absolutely no members in it when using CQRS design pattern.
In such cases, rule S2094 raises.

Repro steps

Consider the following class, which is a totally valid Query.

public class GetAllUsersQuery {}

Expected behavior

I would expect rule S2094 not to raise on such classes.

I would suggest ignoring classes that have known Query suffix

Hi @fraserkyle, thanks for the report!
I confirm this as an FP.

This will require an RSPEC update.
