Update CI for Elixir 1.19.1

[treble37]

• Also, update credo due to error: "could not compile dependency :credo, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile credo --force", update it with "mix deps.update credo" or clean it with "mix deps.clean credo"

Just making a related note wrt the CI failure. Locally, if I run mix test --seed 715375, I get failing test approx every other test run at test/assertions/enum/have_min_by_test.exs:28

The IO.inspect(...) output of context[:success] is:
