[FEATURE] Set default file extensions to be included based on IDEA type

[mydeveloperplanet]

The default file extensions in the settings page contain many file extensions. It should default based on the IDEA type: IntelliJ, Webstorm, CLion, etc.

This can be done via the following check:

import com.intellij.util.PlatformUtils;
boolean isIntelliJ = PlatformUtils.isIntelliJ();

TBD:

• list of product types and default extensions needs to be created.
• how to test and verify this
