Elixir and Erlang/OTP versions

Erlang/OTP 27 [erts-15.2.4] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [jit]

Elixir 1.19.4 (compiled with Erlang/OTP 27)

Operating system

N/A

Current behavior

When a test file is not loaded nor ignored by :test_load_filters and :test_ignore_filters, the following warning is displayed:

warning: the following files do not match any of the configured `:test_load_filters` / `:test_ignore_filters`"

However, this "warning"-prefixed line does not seem to make mix test return a non-zero exit code, even with mix test --warnings-as-errors.

Expected behavior

I think it would be handy if this warning could be considered a warning, like warnings from test files.

Note that I'm open to submitting a PR if this "proposal" is accepted.
