feat: warn users when template deviates from actual variables

[aosasona]

The dotenv package in Deno has a cool feature where it checks the output example env (e.g. .env.example) and warns you if it is different from your current environment file (.env or whatever you are using), would be cool to add this!

Need to check for:

• .env.example
• {file}.example

this is not set in stone yet

thats pretty interesting, is this being implemented?

@devlulcas Unfortunately not yet. I haven't written Gleam in almost two years now. Perhaps when I do again, I will find cause to finally work on this. Happy to merge a PR if you're interested though!
