Temporarily remove OkHttp support in Spring Cloud Gateway Mvc?

[cylx3126]

MRE here

The OkHttp3ClientHttpRequestFactory was deprecated since Spring Framework 6.1 #30919.

Use Okhttp3 in Spring Cloud Gateway Mvc will cause an IllegalArgumentException when route GET methods.

There is no explicit okhttp3 support in gateway. I'm not going to do anything specific to block it, it seems it will let users know with exceptions.
