Enhancement: Add environment variable / pyproject.toml section for AA

[Kumzy]

Summary

Hello,

The idea is to be able to:

1. set environment variable for Advanced-Alchemy, not limited to but for the --config of the cli.

2. add a section in pyproject.toml, same as for environment variable.
   This could look like this

[tool.advanced-alchemy]
config = "path.to.alc.computer.alchemy-config.config"

The goal is that we do not have when using AA, we could omit --config when using it from the terminal with a framework

Maybe create a class to parse the config/toml
