Please add additional search sources for peertube plugin

[ThunderHen]

Please consider looking into alternative or fallback domains for search results for peertube sepiasearch Could be a good alternative for getting search results on a network that filters specific domains or to load balance the requests of people searching for peertube videos. As for the other domains that are listed on this issue, they are more likely to have different videos / instances in the search results.

Just to clarify, the plugin currently uses instance data from https://instances.joinpeertube.org only to check whether a URL belongs to a PeerTube instance.

For searching across instances, we use SepiaSearch, which indexes content from those instances. To achieve a broader search across more instances, a PeerTube instance that follows those instances would be necessary.

To start, I'll look into adding those valid instances to the plugin's list.
