AWS lambda : Spring boot 3 Servlet application having webflux dependency for web client

*To help us debug your issue fill in the basic information below using the options provided*

*Serverless Java Container version*: `2.0.0.M2

*Implementations:* `Spring Boot 3

*Framework version:* `eg SpringBoot 3.1.2`

*Frontend service:* `REST API /ALB`

*Deployment method:* `eg SAM, Serverless Framework, Console`

## Scenario
*Describe what you are trying to accomplish*
I am having Spring boot 3 Microservice deployed as AWS lambda. This microservice contains Webflux dependnecy for Spring Reactive WebClient. I have excluded Netty dependency from WebFlux. AWS Java Serverless library considering AWS lambda as Reactibe but I want it to be Servlet.

## Expected behavior
*Describe how you would expect the application to behave*
Please provide way to set up servlet web application type even it contains web flux dependency.
or
Check if spring web dependency is available, it should be servlet application

Spring is considering Reactive WebClient as synchronous in case spring web dependency is available

## Actual behavior
*Describe what you are seeing instead*

Reactive web application type is considered by library

## Steps to reproduce
*Provide code samples we can use to reproduce the issue as part of our integration tests. If there is a public repository for the misbehaving application link to it here*

handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Class.forName(System.getenv(APPLICATION)));

## Full log output
*Paste the full log output from the Lambda function's CloudWatch logs*

```
logs
```

Start with the `SpringBootLambdaContainerHandler.getAwsProxyHandler(...)` entry point and reproduce the behavior using a Spring Boot 3 application that includes WebFlux while excluding Netty. Trace how the library selects reactive versus servlet mode; done means the application is treated as a servlet application when the Spring web dependency is present.
