Investigate automated test failures

[mattbsox]

Current GHA test profiles are failing. Seeing some different issues:

• Element lookup failures: NoSuchElementError: no such element: Unable to locate element: {"method":"css selector","selector":".monaco-workbench"}
• Element interaction failures: ElementNotInteractableError: element not interactable
• Type/undefined errors: TypeError: Cannot read properties of undefined (reading 'click'), TypeError: Cannot read properties of undefined (reading 'openContextMenu')

The type errors might be related to the previous version change on vscode-extension-tester. The lookup and interaction failures could also be related to the change, or timing/wait inconsistencies.

Missed a version update in #547. Fixed in #549 with Linux tests passing. Still investigating Mac build failures.
