### Region

Canada

### Provide a description that is worded well enough to be understood

[gem.cbc.ca](https://gem.cbc.ca/) **does** support login with password, and **does not** support the use of cookies.

Using the `--username` and `--password` options displays the below incorrect warning message and then works properly.

`WARNING: [gem.cbc.ca:playlist] Login with password is not supported for this website. Use --cookies-from-browser or --cookies for the authentication. See  https://github.com/yt-dlp/yt-dlp/wiki/FAQ#how-do-i-pass-cookies-to-yt-dlp  for how to manually pass cookies`

Using the `-cookies-from-browser` or `--cookies options` results in an error for this site.

SUMMARY
Downloads do work properly from [gem.cbc.ca](https://gem.cbc.ca/) but the warning message is incorrect and provides false information.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
