[BUG] ticks = {Matrix} torpedos pyplot painting

Details

Under Julia 1.7.2, Plots v1.28.1, PyPlot v2.10.0, assigning a 1D {Matrix} to x/yticks prevents the plot from displaying. vscode>Jupyter fails silently while repl gives an error. This can be worked around by xt = vec([1 3 7 10]). GR() is happy with a 1D matrix for ticks.

using Plots
pyplot()
x = 1:1:10
y = 2 .*x
xt = [1, 3, 7, 10]
@show typeof(xt)
p1 = plot(x,y, xticks=(xt,xt), title="typeof(xt)=$(typeof(xt))")

xt = [1 3 7 10]
@show typeof(xt)
p2 = plot(x,y, xticks=(xt,xt), title="typeof(xt)=$(typeof(xt))")

plot(p1,p2)

No type error or warnings are given in vsCode.Jupyter.

Executing in the julia repl gives:

Error showing value of type Plots.Plot{Plots.PyPlotBackend}:
ERROR: Invalid input for xticks: ([1 3 7 10], [1 3 7 10])
Stacktrace: ...

It's good to have any error, but a type error would seem more correct. Any thoughts on why Jupyter doesn't pass on the error?

More generally, can types be added to the documentation display? There's more information in the doc url than in the page https://docs.juliaplots.org/latest/api/#Plots.xticks!-Tuple{Union{Symbol,%20Tuple{AbstractVector{T},%20AbstractVector{S}},%20AbstractVector{T}}%20where%20{T%3C:Real,%20S%3C:AbstractString}}

#2337 may be relevant & blocking.

Many thanks, Ben
