Add tutorial on passing access token to session (good first issue) #1078
Description
Summary of proposed feature
A large number of issues are created that asks how to pass access_token to the session.
Purpose of proposed feature
Currently, we point the users to the jwt and session callbacks documentation, but since it's such a highly requested thing, we might just want to create a specific tutorial under https://next-auth.js.org/tutorials that explains this in details.
Detail about proposed feature
We could either add it directly to the tutorials as a standalone page, or add la link to an external post, preferably with code examples, maybe a working demo app as well, that is live on an accessible url.
Describe any alternatives you've considered
Docs are clearly not good enough, as we are still asked quite a lot.
Please indicate if you are willing and able to help implement the proposed feature.
This is up for grab, marked as a good first issue.
