fix histogram in polaraxes in CairoMakie

[bjarthur]

fixes #3175

tests pass locally.

gemini wrote this. seems reasonable but i'm not that familiar with this part of Makie so please review thoroughly.

#5412 also fixes this iirc

[bjarthur]

#5412 is close! the r axis though doesn't start at 0. is that maybe why it isn't merged yet? is there a workaround using maybe rlimits or rticks?

with this code from #3175

f = Figure()
ax = PolarAxis(f[1, 1])
p = hist!(ax, 2pi .* rand(300), strokewidth = 1, bins = range(0, 2pi, length=37)) # direction = :x for ax.theta_as_x = false
f
