Response Targets extension should be mentioned in the homepage

This one:

https://htmx.org/extensions/response-targets/

Why?

Input validation is The most important thing on a web-app. For example, if a login attempt fails, 401 Unathorized should be the right status code. Returning something like 200 for a failed login attempt is dubious. Like-wise, 422 is a more appropriate response to an invalid form submission than 200. Additionally, following HTMX philosophy, it makes sense to include the error message in the body of the request as HyperMedia.

But HTMX with its current defaults requires a 200 in order to allow swapping.

Also note that merging this extension into htmx's core is being discussed for htmx 2 to have native errors handling support 👀
