title: In Cypress, set a token in localStorage before test
body: <p>I want to login and set a <code>localStorage</code> token on the client (specifically <a href="https://en.wikipedia.org/wiki/JSON_Web_Token" rel="noreferrer"><code>jwt</code></a>)</p>
  
  <p>How can I accomplish this using <code>cy.request</code>, as suggested in the Cypress Documentation?</p>
