Remove --remote-components flags - use bundled yt-dlp-ejs instead

The --remote-components ejs:github flag was causing yt-dlp to attempt
downloading EJS scripts from GitHub. However, Deno runs with --no-remote
flag, blocking all remote access and causing infinite hangs.

Since yt-dlp-ejs is already installed via pip, it will be automatically
detected and used without needing the --remote-components flag.

This fixes the "Getting info" hang issue.
