spring-boot-starter-jetty issue with jakarta on springboot 3.0.0

[luvk1412]

Issue

Using spring-boot-starter-jetty with version 3.0.0, fails when we try to start a jetty server in the application. ClassNotFound exception is seen for class import jakarta.servlet.http.HttpSessionContext.
Explicitly importing the same version of jetty library in 3.0.0 ( 11.0.12) solves the issue. Explicit import is bringing back some parts of jakarta (<6.0) which has the above class.

Steps to reproduce:

• create a project with spring initialiser with spring web, and jetty starter
• Create a bean for JettyServletWebServerFactory to use jetty server
• You would see following error

Caused by: java.lang.NoClassDefFoundError: jakarta/servlet/http/HttpSessionContext

Above can be solved by explicitly mentioning the eclipse version in pom. Ideally this should just work with standard imports, so there is some issues in spring-boot-starter-jetty i think.
