Create GUI test for assigning an issue to a different user than yourself

[wlsf82]

As a test pre-condition, a user has to be created and assigned to the same project of the issue so you can assign the user to the issue.

This user creation must happen via an API call, not the GUI.

This test implementation should help you with understanding how to create a user via API, as well as how to add the user to the same project as the root user.

You can use the following test as a reference: cypress/e2e/gui/project/assignIssue.cy.js

Remember to add the new test to the cypress/e2e/gui/project/index.cy.js file, anywhere between the access token creation and deletion.

If you need more information, don't hesitate to tag me (@wlsf82).

Also, remember to follow the project's contributing guidelines.
