Context

• Decrease the likelyhood of a site-check by Ryte to end in a timeout.

Summary

This PR can be summarized in the following changelog entry:

• [non-user-facing] Increase the timeout for the site-health check to Ryte from 5 to 10 seconds.

Relevant technical choices:

• When Ryte is particularly busy, responses may exceed several seconds. Combine this with WordPress / host / networking overhead may cause the Ryte check to timeout and show an cURL 28 error.
