Cldr Calendars version 1.24.1

Bug Fixes

• Compile on Elixir releases < 1.17. Some code in Cldr.Calendar depends on the new t:Duration.t/0 struct which is only available on Elixir 1.17 or later. Elixir 1.16 is now added to the CI test matrix to ensure no future regression. Thanks to @WernerBuchert for the report. Closes #21.
