[BUG] [dojo-bindgen] [unity] Generated actions methods try to call FieldElements in calldata

[trevis-dev]

Describe the bug
bindgen will generate code trying to call Inner on systems calldata elements.

To Reproduce
Steps to reproduce the behavior:

1. clone dojo-starter
2. run sozo build --unity
3. Inspect Actions's Move in dojo_starter::systems::actions::actions.gen.cs which shows

calldata = new dojo.FieldElement[] {
    new FieldElement(direction).Inner()
}

Which doesn't compile.

Expected behavior
The resulting code should be

-    new FieldElement(direction).Inner()
+    new FieldElement(direction).Inner

Additional info
It seems that format_system always formats calldata with FieldElement({}).Inner()

dojo/crates/dojo-bindgen/src/plugins/unity/mod.rs

Lines 209 to 234 in 010444f

	match handled_tokens.iter().find(|t| t.type_name() == token.type_name()) {
	Some(t) => {
	// Need to flatten the struct members.
	match t.r#type {
	CompositeType::Struct => t
	.inners
	.iter()
	.map(|field| {
	format!(
	"new FieldElement({}.{}).Inner()",
	type_name, field.name
	)
	})
	.collect::<Vec<String>>()
	.join(",\n "),
	_ => {
	format!("new FieldElement({}).Inner()", type_name)
	}
	}
	}
	None => match UnityPlugin::map_type(type_name).as_str() {
	"FieldElement" => format!("{}.Inner()", type_name),
	_ => format!("new FieldElement({}).Inner()", type_name),
	},
	}
	})

I'm guessing it should probably just be Inner everywhere. If confirmed, I'd be happy to make a PR.
