Adding Extra Logs for Config Reading Behaviour

[matheusgomes28]

Improves the logs for #516 . After looking into the codebase, I understand that the following behaviour is intended:

1. read .air.toml if available.
2. failing above, read .air.conf if available.
3. failing above, use default configs.

The issue is that the user currently has no idea if they simply run air from their repo, with an invalid .air.toml. It is 100% clearer to log the behaviour so the user doesn't waste time (like I did) wondering why my .air.toml settings weren't picked up !

Is air still under development? I can close PR if you guys aren't taking any more features

@matheusgomes28 Thanks for your PR. Air is indeed still being maintained, though it is currently not in a phase of active development. We will periodically address issues and pull requests in batches.
