Spotify regex does not support http

[GuilhermeVieiraDev]

In the constant REGEX in the plugin.ts file, the regex does not support the spotify url with http, only https.
So my suggestion is to update the regex to this one.

/(?:https?://open.spotify.com/|spotify:)(.+)(?:[/:])([A-Za-z0-9]+)/

I doubt this will ever be used but I suppose it's best to have it than not to.
