+This class is not perfect but it does serve our needs.
+see the comments in com.intellij.util.PlatformUtils, PlatformUtils is marked internal API so its better not to user it.
+for what we need its probably ok:
+isIdeaIDE() is for sure Idea if we have JavaLanguageService installed.
+isRiderIDE() is for sure rider if we have CHarpLanguageService installed.
+isPyCharmIDE() is for sure pycharm if we have PythonLanguageService installed and it's not Idea.
+if we need more capabilities here we need to explore the technics suggested in com.intellij.util.PlatformUtils
