Name with uppercase on highway=bus_stop

[Gafigglethorp]

In Greece, the community consensus is that bus stop names are rendered in all caps.

This is the standard way to render them in all user facing applications: Transit maps, the stop itself, bus route diagrams, digital maps inside the buses themselves or online, transit applications, and more.

It is also documented in the wiki here.

This has caused literally (tens of?) thousands of false positives across Greece.
