Use more descriptive names for examples

[molant]

The current list of examples is based on a list of PWA features.
We should be using more descriptive titles in some of the cases because in many instances the feature might be called slightly different or the developers might not know what they are exactly looking for and the name might not be enough.

Note that there is already an alias list. This list is used to decide the folder for the example and we should have another value (the map could use an object instead of a string, or something completely different).
