Display an error message in the Cypress app when WebKit cannot launch on this MacOS version
What would you like?
I would like a clear message that WebKit cannot be launched on my MacOS version. Currently, I select WebKit and click the green Start button, which turns gray and says "Opening E2E Testing in Webkit", and then nothing happens.
I figured it out when I tried cypress run instead of cypress open. In this case, I got a very clear message that immediately explained the problem:
There was an error launching `playwright-webkit`:
```Browser closed.

Why is this needed?
I had no idea why WebKit wasn't opening. Sometimes the Cypress app is slow to open a browser so I waited several minutes to see if it resolved itself. I didn't know if I had installed the wrong thing, or screwed up the config, or if maybe it was a case of "it takes longer to run the first time".
