Make `isapprox` error unless shapes match

[jariji]

I don't like this and I would like it to error

julia> [1; 2; 3;;]
3×1 Matrix{Int64}:
 1
 2
 3
julia> [1; 2; 3;;] ≈ [1,2,3]
true

just like this does

julia> (x for x in 1:3) ≈ [1,2,3]
ERROR: MethodError: no method matching isapprox(::Base.Generator{UnitRange{Int64}, typeof(identity)}, ::Vector{Int64})

Possible course of action: make a PR then request a PkgEval from NanoSoldier to see what will break.

I would like it to error

Given that == returns false for array arguments of mismatched shape, perhaps [1; 2; 3;;] ≈ [1,2,3] should return false, too?

[jariji]

I think Matrix == Vector should error too. https://github.com/JuliaLang/julia/issues/40717

[nsajko]

Yeah, but that's definitely for a breaking release.
