Fix intellij plugin installation

[jan-vcapgemini]

Expected behavior

As an IDEasy intellij user I expect IDEasy to install and activate plugins for intellij properly if the active flag is set.

Actual behavior

IDEasy downloads the plugins to the project/plugins/intellij folder but does not activate it automatically.

Steps to reproduce (bug) / Use Case of feature request (enhancement)

1. Modify the settings/intellij/plugins/ files and activate a plugin
2. Start intellij by typing ide intellij
3. Check if the plugin was activated in intellij
