resolve CairoMakie insert! ambiguity

[aplavin]

Description

Before:

julia> plotlist([Makie.SpecApi.Scatter(1:10)])

julia> plotlist!([Makie.SpecApi.Scatter(1:10)])
ERROR: MethodError: insert!(::CairoMakie.Screen{CairoMakie.IMAGE}, ::Scene, ::Plot{Makie.plotlist, Tuple{Vector{PlotSpec}}}) is ambiguous.

Candidates:
  insert!(screen::CairoMakie.Screen, scene::Scene, plot)
    @ CairoMakie ~/.julia/packages/CairoMakie/wKKMp/src/screen.jl:206
  insert!(::MakieScreen, ::Scene, ::Plot{Makie.plotlist})
    @ Makie ~/.julia/packages/Makie/rEu75/src/specapi.jl:387

Possible fix, define
  insert!(::CairoMakie.Screen, ::Scene, ::Plot{Makie.plotlist})
