lang/dhall: Update to 1.41.2

1.41.2
* BUG FIX: Fix :hash REPL command to α-normalize input
* Add {From,To}Dhall instances for DayOfWeek
* Add {From,To}Dhall instances for ShortText
* Performance improvements
* Fixes and improvements to haddocks
* Fixes and improvements to test suite
* Build against newer dependencies

1.41.1
* BUG FIX: Don't escape ? path component when pretty-printing with
  expressions

1.41.0
* Support standard version 22.0.0
  - Allow with expressions to update Optional values using ?
  - Add showConstructor keyword
* BUG FIX: Fix pretty-printing of time zones
  - Timezones with a negative offset were previously being rendered with
    two leading minus signs instead of one
* BUG FIX: dhall freeze --cache to work with standard version 21.0.0
  - dhall freeze will now use missing sha256:… for the first import so that
    the latter import will be tried if the import is not in cache
  - The old behavior is incompatible with standard version 21.0.0 because
    the new behavior of the ? operator doesn't fall back on hash mismatches
* BUG FIX: Allow with expression to update a field named Some
  - This fixes a discrepancy between the Haskell implementation and the
    standard where the Haskell implementation would not permit { Some = 0 }
    with Some = 1
* Fix dhall {format,lint,freeze} to preserve leading shebangs
* Add FromDhall instances for Int{8,16,32,64}
