[🐛 Bug]: HelmChart should use /readyz endpoint to check the health - so that k8s can restart a failed grid

[Bjego]

What happened?

The Http statuscodes for the /readyz endpoint have been adjusted (SeleniumHQ/selenium#10391). The status endpoint as you can see in the Selenium ticket returns always 200 - Ok even if the grid isn't running properly.

We should adjust the helmchart to use the readyz endpoint for health checks. So that kubernetes can restart the grid on it's own.

I think I can give it a quick shot, do all components expose the /readyz endpoint?

Guess I'm too late. Was busy this week doing features at work. Thanks for implementing it!
