Describe the bug

I'm trying to install a configuration package with remotes, profiles and user_settings.yml in my CI/CD pipeline, but when I use conan config install-pkg mtx-config/1.0.0 --url <url> it fails because of authentication.

I've tried using --url https://${user}:${token}@${server} but this doesn't help.
I also already have the CONAN_LOGIN_USERNAME_<REMOTE> and equivalent TOKEN environment variable set where <REMOTE> is _tmp_conan_config but that didn't work either.

The only way I could do this was to use set the username/token in the CONAN_LOGIN_USERNAME and CONAN_LOGIN_TOKEN env vars.

This is OK, but not ideal.

How to reproduce it

Just try to add a config from a remote which requires authentication using: conan config install-pkg mtx-config/1.0.0 --url <url>.
