Subject: [PATCH 4/4] Update check_zygote_type_stability()... (#568)

so that CI passes with Julia v1.10. Tested locally with Julia v1.10 & v1.11. Forces the expected type to be `Vector{Union{Nothing, @NamedTuple{X::Matrix{Float64}}}}` which is more robust for different package versions. There may be better solutions, but this seems to work.
