This upgrade replaces the passwords stored in env variables by docker secrets.
You need to insert the following passwords as secret:

`POSTGRES_PASSWORD` / `AUTHENTIK_POSTGRESQL__PASSWORD`:
    `abra app secret insert <app_name> db_password v1 <password>`
`AUTHENTIK_SECRET_KEY`:
    `abra app secret insert <app_name> secret_key v1 <password>`
`AK_ADMIN_TOKEN`:
    `abra app secret insert <app_name> admin_token v1 <password>`
`AK_ADMIN_PASS`:
    `abra app secret insert <app_name> admin_pass v1 <password>`
`AUTHENTIK_EMAIL__PASSWORD`:
    `abra app secret insert <app_name> email_pass v1 <password>`

These variables should be removed from the .env file.
