function-sample-azure-web fails at runtime with Spring Boot 4.0.0 due to incompatible Spring Cloud Function dependencies

[purohitdeep]

Describe the bug

function-sample-azure-web

The application fails during initialization with a runtime exception (e.g. NoClassDefFoundError related to Spring Boot internals such as DefaultBootstrapContext).

Dependency inspection shows incompatible major versions being pulled in simultaneously:

• Spring Boot 4 APIs being used with Spring Cloud Function code built for Boot 3.x
• Mixed Jackson 2.x and Jackson 3.x artifacts on the classpath

The sample should either:

• Use Spring Boot 3.x with a compatible Spring Cloud Function 4.x release
  OR
• Be updated to a Spring Cloud Function version compatible with Spring Boot 4

Sample

1. Navigate to sample: spring-cloud-function-samples/function-sample-azure-web
2. ./mvnw azure-functions:run
3. curl -X GET http://localhost:7072/api/AzureWebAdapter/
