Bug: Parameters issues

[Aymkdn]

Describe your issue

Hello,

Thanks for this project!

I've just installed it on Windows 11 with Node 20 and I noticed that the command provided as an example returns an error:

> npm run grab -- --site=chaines-tv.orange.fr
Error: One of the arguments must be presented: --site or --channels

To make it work, I have to type:

npm run grab -- -- --site chaines-tv.orange.fr

Notice the double --, as well as the space between --site and the site name.
