Draft: Fix YouTube embeds by rewriting http to https
YouTube video embeds no longer work in Pleroma.
It turns out YouTube broke their own oEmbed implementation and haven't fixed it in months. See: https://github.com/oscarotero/Embed/issues/417#issuecomment-746673027
If we want the ability to embed YouTube videos, we need to rewrite the URLs they provide from http to https.
