bug: Spotify Integration Not Working

[drewjenkins]

It looks like Spotify recently updated their access token handling logic.

Before:
https://github.com/pluto/attest-integrations/blob/main/integrations/spotify-top-artists/v3/prepare.js

They would store their access token int he DOM under a script tag.

Now:
They use a refresh token to an initial call to a /get_access_token endpoint to retrieve an access token, and store it in memory. From what I can tell they don't store the access token anywhere other than in memory.
