Create script for local end-to-end testing

[hohwille]

Task summary

This story is about creating a (bash) script that automate the build and installation of the local IDEasy code-base:

• build IDEasy (see step 3 of https://github.com/devonfw/IDEasy/blob/main/documentation/contributing/graalvm-build-guide.adoc)
• include the assembly for windows if easily possible
• delete $IDE_ROOT/_ide/software/maven/ideasy/ideasy/local-dev if it exists
• create the folder $IDE_ROOT/_ide/software/maven/ideasy/ideasy/local-dev
• copy the package contents to the newly created, empty local-dev folder (ideasy[.exe] goes to bin subfolder)
• finally update the symbolic link $IDE_ROOT/_ide/installation to the new local-dev folder (you could use ideasy ln -s ... command for that).

So after running the script successfully, I can call ide ... commands and will test the native image and local code I just build. This should make it easier to do e2e testing (e.g. for auto-completion change, etc.).

Additional context

To go back developer can simply do ide upgrade --mode=stable (and potentially ide upgrade --mode=snapshot)
