Feature: support hinting from .env.example files

[G-Rath]

A lot of projects that have .env files use .env.example as the example file, rather than provide an actual .env.

It would be cool if this plugin supported reading .env.example files, using them to generate suggestions when editing .env files.

Sorry, I'm not sure I understand the use-case clearly. Can you explain it in more details please?
