Document layer names on the Rendering Tutorial page

[pcmill]

I followed the tutorial to create the map style I wanted to achieve and found myself not knowing how the different layers are called. I eventually found this code: default_style which solved my personal problem.

Might be nice to create a list on the tutorial page (or elsewhere) so people can quickly start styling their own maps. Also documenting which Symbolizer you need for each layer could be useful. So boundaries is used with LineSymbolizer and earth is used with PolygonSymbolizer etc.

Last thing that would be really useful is a list of the different props that can be useful to filter. For example I used pmap:min_admin_level === 2 to only show country boundaries.

Just found https://protomaps.com/docs/map-layers-tags. Then linking this page on the tutorial page might be enough :)

I've re-organized the Docs site completely:

https://protomaps.com/docs/frontends/basemap-layers contains the basemap layers

https://protomaps.com/docs/frontends/leaflet#custom-vector-data contains the old "tutorial" for writing Symbolizers.

Will add some more links to/from GitHub and info on the possible props values. Thanks for the feedback!
