[TypeScript] miss some export in index.ts

[XHanL]

Typescript library missing some export.

The scheme SchemeRainbow, SchemeFruitSalad are missing.
The enum Variant is also important when we try to create a DynamicScheme.

Example

import { type Variant, SchemeRainbow, SchemeFruitSalad } from "@material/material-color-utilities";

Example Error

Module '"@material/material-color-utilities"' has no exported member 'Variant'.ts(2305)
Module '"@material/material-color-utilities"' has no exported member 'SchemeRainbow'.ts(2305)
Module '"@material/material-color-utilities"' has no exported member 'SchemeFruitSalad'.ts(2305)

index.ts missing export

export * from "./scheme/variant.js";
export * from "./scheme/scheme_rainbow.js";
export * from "./scheme/scheme_fruit_salad.js";

In the meantime:

// Copies from @material/material-color-utilities instead of importing
// `import Variant from '@material/material-color-utilities/scheme/variant';
// Because it's not exported from the package
export enum Variant {
	MONOCHROME,
	NEUTRAL,
	TONAL_SPOT,
	VIBRANT,
	EXPRESSIVE,
	FIDELITY,
	CONTENT,
}
