[Deprecation warnings] use Base.getindex(A, :, i) instead. & Change A[i] to A.u[i]

[prbzrg]

By new versions, I am getting:

┌ Warning: `Base.getindex(A::AbstractDiffEqArray, i::Int)` is deprecated, use `Base.getindex(A, :, i)` instead.

There are some others too in the CI.

Yes, there's a lot of updates to do for RAT v3

[matthewelmer-tamu]

As a user that is getting this warning, how do I make it go away?

[ChrisRackauckas]

Set depwarns to error, i.e. julia --depwarn=no, and then change the spot where it errors to sol.u[i] instead of sol[i].

Should we close this?
