Enum.min_max should take a sorting function

[flexagoon]

Elixir and Erlang/OTP versions

Erlang/OTP 28 [erts-16.0.2] [source] [64-bit] [smp:20:20] [ds:20:20:10] [async-threads:1] [jit:ns]

Elixir 1.18.4 (compiled with Erlang/OTP 27)

Operating system

Linux

Current behavior

All Enum min/max functions (i.e. Enum.min, Enum.max and Enum.min_max_by) have an overload that takes a sorting function, allowing to sort structs with a compare method, like dates. However, Enum.min_max doesn't have an overload like that and doesn't allow a custom sort function.

Expected behavior

{min_date, max_date} = Enum.min_max(dates, Date)

This should be possible

A pull request exploring an API compatitle with min_max is welcome.
