Functional Test: Mobile - Sidebar Navigation to Join Team

[gcardonag]

Is your feature request related to a problem? Please describe.
As a PHLASK developer, I would like to have automated testing of navigating to the "Join Team" view in the sidebar so that this functionality works consistently throughout any future site development.

Describe the solution you'd like

1. Add a Cypress test that performs the following actions in cypress/e2e/mobile/menuNavigation.cy.js
   1. Click on the "Sidebar"/hamburger button on the top toolbar
   2. Click on the "Join the Team" option on the menu
   3. Confirm that the top header text in the sidebar shows "Join the team"
2. If necessary, add data-cy attributes to resources in order to allow Cypress to target them for clicking/writing/etc.
   • For an example of how to target elements, see the the should successfully submit a water site for testing test in the cypress/e2e/desktop/crowdsourcing.cy.js file.
   • For an example of how components are updated to support the example above, see line 27 of the src/components/AddResourceModal/ChooseResource.jsx file.
3. When opening a Pull Request for this story, make sure to include a video recording of the completed test to help reviewers.
   • When you run tests locally, a video of the test should automatically be recorded in the cypress/videos folder.
