Remove light switch from lighting-app (#15118)

Endpoint 2 in lighting-app.zap is missing the descriptor cluster which
is mandatory.

Since the "light switch" sample is now available, presumably we don't
need a switch endpoint on the "light" samples, so remove it rather than
add the missing cluster.
