[bug#66801] [PATCH va3e5ae0f..37252e07 02/32] gnu: erlang updated.

["Pierre-Henry Fröhring" <phfrohring@deeplinks.com>]

Wrapped Erlang programs (`erl`, `erlc`, `escript`) now prepend ERL_LIBS with
GUIX_ERL_LIBS. Reference: https://www.erlang.org/doc/man/code#code-path. The
`native-search-paths` field in the package specification sets GUIX_ERL_LIBS,
which aggregates all compiled libraries for Erlang and Elixir, akin to the
functionality of GUIX_PYTHONPATH.
