generate turso:// URLs for Turso databases

Databases identified as Turso (via the UUID type byte) now display
turso:// URLs instead of libsql:// in db list, db show, and the shell
banner. The built-in shell also accepts turso:// URLs, rewriting the
scheme to libsql before handing it to libsql-shell-go, which only
understands libsql/ws/http schemes.

The shell library is quite legacy at this point, and we should be
moving the CLI to the tursodb binary anyway, so for now we just hack
the scheme rewrite here rather than teaching the library about
turso://.
