Camel Debugger - Avoid relying on a custom location of the build and settings gradle files

The fixes for #641 rely on command line options that are deprecated in Gradle 8 and will be removed in Gradle 9 see https://docs.gradle.org/8.0.1/userguide/upgrading_version_7.html#configuring_custom_build_layout

The goal of this task is to rewrite this part of the code to be compatible with future versions of Gradle. One option could be to use a specific directory to store the generated build and settings gradle files but it would also mean that the paths need to be rewritten dynamically which can be tricky.
