[Bug] rename safegraph example to mapbox

[chrisgervang]

Description

While working on #8146 I came across our safegraph example. Its one of our best examples for demonstrating interleaved basemap rendering with mapbox. For discoverability I think it should be renamed to mapbox. safegraph is the source of the data, however it's not super clear how it relates to mapbox.

Our website calls this example Mapbox: https://deck.gl/examples/mapbox

@Pessimistress I'd like to do this rename to reduce confusion. Should I make a PR either move or add the example's data to a mapbox folder in https://github.com/visgl/deck.gl-data/tree/master/examples/ as well?

Discussed offline with @Pessimistress: we're not going to touch deck.gl-data since that would break links on old branches. I will rename the example in deck to mapbox.
