misc: Fix some a11y violations using Cypress Cloud

[jennifer-shehane]

Additional details

Playing around with our early access accessibility checks in the Cypress Cloud to see what the workflow is like to fix them and maybe fix some violations also.

Fixing the following a11y violations found in the Cloud.

• Update role of controller for aria-expanded to correct 'button'. Source
• Missing role attribute for child of listbox parent. Source
• Missing alt text on images: Source
• Add aria-label for readonly input with no label. Source
• Add title to our iframe stub to reflect updates in Cloud iframe title: https://github.com/cypress-io/cypress-services/pull/7299

Steps to test

This upped our a11y coverage on the launchpad tests from 98% to 99% (excludes contrast color checking for now)
