Fix NoSuchMethodError thrown by ClientResponseFunctionInterceptor in reactive plugin.

[JooHyukKim]

Motivation

This PR fixes NoSuchMethodError thrown by ClientResponseFunctionInterceptor.
To be specific,

java.lang.NoSuchMethodError: `int org.spring....<rest-ommitted>.reactive.ClientHttpResponse.getRawStatusCode()`

Explanation

My application runs on SpringBoot 3 uses 6+ version of spring-reactive where there is no getRawStatusCode().

I understand that as per Pinpoint version 2.5.x README file, it says

* Range: org.springframework/spring-webflux [5.0.0.RELEASE, 5.3.max]

... saying it does not need to conform to version range out of range.
But since there is already method getStatusCode() from which we can achieve the same functionality, there is no reason not to use getStatusCode() instead.?

Note

I simply chained ...

response.getStatusCode().value()

... because it's never null.
LMK if we prefer null check.

May I ask if 2.5.x version is still in maintained, @emeroad? I am asking this because it seems like only PR's against 3.x version have been merged.

Great, I was wondering if we should suggest backporting that commit 🙏🏼🙏🏼
Looks better than this fix, thank you!

May I ask when 2.5.4 is expected to be released?
If it takes too long, we are considering to build and use latest 2.5.x version with the patch.
