The documentation incorrectly tells users to use access tokens from clients

The documentation still tells users to fetch access tokens for Draupnir from a client such as Element Web. This was already not good advice (albeit the simplest solution) however now that servers are starting to roll out OIDC and MAS, these tokens are also now becoming short-lived. Including the cURL command, or linking to something similar to my access token fetcher should probably be done going forward.
