incomplete_raw_credentials thrown when requesting a Slack user token

Export

## The problem

Triggering a Nango connection for Slack with user scopes via authorization_params throws incomplete_raw_credentials, because the SDK only handled the bot token path and dropped the user token. Users who need the Slack user token from oauth.v2.access could not get one.

## The fix

Fixed upstream in Nango PR #4025. Update Nango to a version containing that fix and user-scope connections return the user token properly.
