Change Map to List to use the same command option multiple times

[JunkFood02]

Many command options of yt-dlp can be used multiple times, e.g --parse-metadata here.

Using Map instead of List for saving commands makes multiple usages of the same options impossible, which will only store the last value stored for the same key.
