[tz] [Change] DST dates for Chile will change in 2022-2023

Hello there: As of moments ago, the Internal Affairs Ministry (Ministerio del Interior) informed DST for America/Santiago will start on midnight of September 11th; and will end on April 1st, 2023. Magallanes region (America/Punta Arenas) will keep UTC -3 "indefinitely" If I recall correctly, this might alter at least the switch for 2023 This is because on September 4th we will have a voting whether to approve a new Constitution Source: https://twitter.com/min_interior/status/1556981967551209472
