Wrong springboot version for reverse proxy faq

[Mayeul-T]

In the docs/faq.html file, line 582, you mentione "Spring Boot 3.2".
I think this is an error because server.forward-headers-strategy configuration is available since Spring Boot 2.0.

I don't know how I can create pull request but you should fix that.

Sincerely

I created a PR ( #70 ), but this will be automatically solved as soon as #72 is closed.
