[BUG] surface not working with PyPlot or PGFPlots backend

[RodolfoFigueroa]

Details

When trying to use the surface method with the PyPlot backend, the error KeyError: key :cbar_width not found is thrown.

For completeness, I also added the bug with PGFPlots, already reported in #3248.

Not sure if related but I get the same error KeyError: key :cbar_width not found when setting the zcolor parameter in 3D plots with PyPlot backend. Happened after upgrading from Plots.jl 1.10.4 to 1.10.5 .
