Raise DataInterpolations floor to 9.2

Please ignore this PR until it has been reviewed by @ChrisRackauckas.

What changed

extras DataInterpolations [compat] 9 → 9.2. No code or package version change.

Why

Default-branch Downgrade is red while Tests are green (run). test/sources.jl BSplineInterpolation calls the 4-arg form (u, t, d, knotVecType). DataInterpolations 9.0.0 / 9.1.0 only expose a 5-arg (u, t, d, pVecType, knotVecType). 9.2.0 dropped pVecType and restored the 4-arg method this package uses.

Verification

CI fail-before: MethodError: no method matching BSplineInterpolation(::Vector{Float64}, ::Vector{Float64}, ::Int64, ::Symbol) on DataInterpolations 9.0.0.

Not verified here: the full MTKSL suite or a live julia-downgrade-compat run.

Local isolated-depot proof on Julia 1.10.11 (fail-before / pass-after):

• DataInterpolations.BSplineInterpolation(rand(8), collect(1.0:8.0), 3, :Uniform) on 9.0.0 → MethodError: no method matching BSplineInterpolation(::Vector{Float64}, ::Vector{Float64}, ::Int64, ::Symbol)
• same call on 9.2.0 → OK
