ScopedValues.get(::ScopedValues.ScopedValue) performs a very similar role as Base.get(collection, index, default) and I think they should have the same API and name, i.e. rename ScopedValues.get to Base.get and make its API conform to the Base get API.

Right now, ScopedValues.get is it's own generic function, distinct from Base.getindex and from Base.get.

ScopedValues was introduced in 1.11, so this needs to be done before the 1.11 release if we want to do it at all.

Reading #50958, I don't see any explicit discussion about this name, but perhaps I'm missing something.
