refs https://ghost.slack.com/archives/C02G9E68C/p1665043198507819?thread_ts=1664955131.950719&cid=C02G9E68C

- this adds support for `yarn dev --stripe` which will spin up the
  Stripe CLI to listen for webhooks, and configures Ghost with the
  secret key it needs to communicate
- also fixes a minor typing error with a missing `env: {}`
