Method ambiguities reported by Aqua

[prbzrg]

In Julia v1.10, I used Aqua to detect method ambiguities in my package impICNF/ContinuousNormalizingFlows.jl#356 and some of its report were related to this package:

Ambiguity #75
fill(v::CategoricalArrays.CategoricalValue{T}, dims::Tuple{Vararg{Integer, N}}) where {T, N} @ CategoricalArrays ~/.julia/packages/CategoricalArrays/0yLZN/src/array.jl:505
fill(v, dims::Tuple{}) @ Base array.jl:585

Possible fix, define
  fill(::CategoricalArrays.CategoricalValue{T}, ::Tuple{}) where T

I would appreciate your attention to this issue.
