Update target platform to 2024-09

[frankbenoit]

javax to jakarta, jetty 10.x to 12.0.12

What it does

Update to Eclipse target platform 2024-09.

How to test

The target platform state show no errors.
My test application did startup without exceptions and worked.

Follow-ups

I updated many versions, probably the ranges should be wider. Or support for older versions is dropped?

Hi @frankbenoit,
thank you for your PR. Unfortunately I run into errors when trying to test this.
As you mentioned the targetplatform resolves without any errors but starting the application (in websocket mode) does not work.
On startup I receive the following error

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/jetty/http/MimeTypes$Mutable

I can solve this by explicitly adding org.eclipse.jetty.http as a dependency to the websocket package.
However, then I run into the following error:

Any ideas what could be the issue here?

@frankbenoit Thanks again for providing this PR. I'm going to merge it into a separate branch so that I can push changes on top.
(minor refactorings in target platform, version adjustments and fixing the plain maven build)
