Describe the bug

Remappings are auto detected twice when loading a foundry_config::Config through load_config, in different ways.

1. Config::with_root builds a default ProjectPathsConfig which detects remappings

   foundry/crates/config/src/lib.rs

   Line 1626 in 759b7d6

   let paths = ProjectPathsConfig::builder().build_with_root::<()>(root);

2. Config::to_figment uses RemappingsProvider which has different logic of auto detection

   foundry/crates/config/src/providers/remappings.rs

   Line 226 in 34ab235

   .flat_map(|lib| Remapping::find_many(&lib))

Both are called in load_config through Config::figment_with_root

foundry/crates/config/src/lib.rs

Lines 1598 to 1600 in 759b7d6

	pub fn figment_with_root(root: impl AsRef<Path>) -> Figment {
	Self::with_root(root.as_ref()).into()
	}

not exactly sure we need this step

foundry/crates/config/src/providers/remappings.rs

Line 211 in 34ab235

// scan all library dirs and autodetect remappings

because this scans the remappings in libs
