[chore] update go-structr and go-mangler to no longer rely on modern-go/reflect2 (#3026)

* updates go-structr and go-mangler to no longer rely on modern-go/reflect2 (*phew* now we're go1.23 safe)

* update go-structr version

* bump go-structr to improve memory usage (v. slightly) in certain conditions
