Currently if a develop names a file with a .yml extension, the file will not be picked up. It will only pick up files with a .yaml extension.

In the development ecosystem at large it is common for developers to use .yaml and .yml. It causes confusion and obstacles for devlopers when they try to use Magnolia and don't understand why their definitions are not being loaded.

To reproduce:

• create or copy a valid dialog definition file and name it 'canyouseeme.yml' and place it in a light modules 'dialogs/components' directory.
• Note that Magnolia does not detect it.
• Rename it to 'canyouseeme.yaml'
• Note that Magnoila detects it.
