8242077: Add information about HTTP/2 and HttpClient usage in WebEngine

[abhinayagarwal]

Update WebEngine's Javadoc to add information on how it switches to HttpClient instead of URLConnection in JavaFX 14 when used with JDK 12 or later.

Identification of the correct client is important as both these clients may offer different ways to achieve a task. One such task can be bypassing insecure HTTPS connection.
