Describe the feature you want

Till #3525 is fixed, it will be great if Newpipe can provide an RSS feed button on top of youtube playlists just like it shows on top side of channel page, the RSS feed looks like this https://www.youtube.com/feeds/videos.xml?playlist_id=YOURPLAYLISTIDHERE

Is your feature request related to a problem? Please describe it

I want to subscribe to playlist. Currently it is kind of a long process since I have to edit the url of playlist, a simple RSS feed button in playlist would be nice.

Additional context

None

How will you/everyone benefit from this feature?

Save time in subscribing a playlist if you are using an RSS feed reader, until Newpipe natively supports subscribing to playlists.
