[simulot]

The communication between, immich-go and the current version of immich server should be tested before merging a PR or whenever an new version of the server is released.

To initiate the communication with a freshly installed server, an admin user must be created as it is done for the demo app: https://github.com/immich-app/demo/blob/main/demo-restart.sh

1- Create the admin user using /auth/admin-sign-up endpoint 2- Log in as admin, get the token 3- Create an API key
