Docs should show available markers and linestyles

[Datseris]

One thing I find extremely convient about pyplot is how it showcases the available markers and linestyles, and this result is directly obtainable by googling "pyplot marker styles". E.g.: https://matplotlib.org/3.2.1/api/markers_api.html

I think it would be equally usefull for Makie to have this as well.

I guess we could do this on a new page and add an example. Will also mention that you can use arbitrary chars (but not strings).

Note there's available_marker_symbols() that could be convenient for this (docs).

[Datseris]

Yeah I ended up finding this function eventually. It should be more exposed and definitely actuially run in the docs, so that users can see the output. However, I would argue it is better to both show the output of the function (so that users know the exact input code for any marker), but also use the function for a scatterplot with all markers.

also available_marker_symbols is not re-exported by backend, say, CarioMakie. One needs to:

CairoMakie.Makie.available_marker_symbols()

Is someone working on this issue? Would it be helpful if I did?
