fix(types): remove void from SharedRenderProps component type

[cyphercodes]

Summary

Fixes #4061

The component prop in SharedRenderProps interface had an incorrect TypeScript type that included void in the union (React.ComponentType<T | void>). This caused TypeScript errors when using properly typed components with FieldArray or other components using SharedRenderProps.

Problem

When using the component prop with a properly typed component, TypeScript produced false errors because it expected the component to accept void as props:

interface MyComponentProps {
  form: FormikProps<any>;
  name: string;
  push: (obj: any) => void;
}

const MyComponent: React.FC<MyComponentProps> = (props) => { ... };

// TypeScript error: Type 'FC<MyComponentProps>' is not assignable to type 'ComponentType<FieldArrayRenderProps | void>'
<FieldArray name="items" component={MyComponent} />

Solution

The component always receives the props of type T at runtime - there's no code path where it receives void. The type has been corrected to React.ComponentType<T>.

Changes

• Changed React.ComponentType<T | void> to React.ComponentType<T> in SharedRenderProps interface

Verification

• TypeScript compilation passes
• No breaking changes - this is a type fix that makes the types match runtime behavior
