[PATCH dtv-scan-tables] dvb-t/hk-HongKong: update Hong Kong digital terrestrial TV scan table

The Hong Kong scan table contains outdated UHF mux frequencies and
broadcaster-specific entries for long-defunct services (e.g., ATV).

Update dvb-t/hk-HongKong to match the latest official frequency
table published by the Office of the Communications Authority (Hong Kong):
