In #102789, `Probes` become `std::vector<std::reference_wrapper<MCDecodedPseudoProbe>>`.
`auto` would expand to a reference_wrapper, so to access the underlying pseudo probe, it would need explicit `get`. To avoid that, we can use `reference_wrapper::operator T&` which is functionally identical to `get`. This is achieved by providing `MCDecodedPseudoProbe &` as type of a range-based variable.
