Review Comment:
@ajfabbri it seems like
https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-servlet/9.4.58.v20250814/dependencies
needs this dependency - so it is best that we don't remove the ability to get
download the dependency.
The aim of this PR is to reduce the number of jars that the Hadoop code
relies on directly.
> Drop use of jetty-util-ajax and use jackson instead

> Hadoop uses jetty-util-ajax in a few modules to read and write JSON.
> This lib is abandoned and it is easy to switch to Jackson.
> This is a part of HADOOP-19912 that can be split out and it doesn't cause the
> same issues with worrying about jar compatibilities - it actually simplifies
> the build by removing a dependency.
