Ruby: WIP: Make Argument[any] and any-named work
It's not fully working I think the problem is that the code below ties up `Argument[x]` with parameter positions, and `Parameter[x]` with argument positions. This flip might be correct for flow-summaries, but it does NOT seem to be correct for the `path` component in MaD. Specifically, quick-eval for ParameterPosition does NOT include `keyword key` while quick-eval for ArgumentPosition DOES include `keyword key`! For the test `Foo.sinkAnyNamedArg(key: tainted) # $ MISSING: hasValueFlow=tainted` https://github.com/github/codeql/blob/c8be8d30b3be15a54921a371e9b41f8c61dec87b/ruby/ql/lib/codeql/ruby/frameworks/data/internal/ApiGraphModelsSpecific.qll#L130-L133
