Improve snforge_std api

[kkawula]

Which components does the task require to be changed? (think hard pls)

snforge

Description

https://github.com/foundry-rs/starknet-foundry/blob/master/snforge_std/src/_config_types.cairo packaged should be quasi private i.e. reexported by _internals

As shown here:

starknet-foundry/snforge_std/src/lib.cairo

Line 137 in 8ce451e

pub mod _config_types;

TODO:

• Move _config_types package to be reexported by _internals
• Update tests that use the _config_types (should be easily searchable in repo)
