Timezone Asia/Calcutta no longer recognized in 17.5+

[H4kor]

The timezone "Asia/Calcutta" was renamed to "Asia/Kolkata" many years ago. However the old name is still used by many system (for example Google Chrome)

Postgres Docker versions 17.5+ no longer recognize "Asia/Calcutta" as a valid time zone.

select now() at time zone 'Asia/Calcutta'

results in: SQL Error [22023]: ERROR: time zone "Asia/Calcutta" not recognized
