[TypeScript] SpecVersion is not properly exported

[Nerwyn]

SpecVersion is not properly exported, which makes using DynamicScheme constructors a little messy as we have to cast inputs to 2021 | 2025 instead of the imported SpecVersion type. We could import directly from the color_spec.js file, but this doesn't work with tsconfig moduleResolution set to bundler.

Adding export * from './dynamiccolor/color_spec'; to the root index.ts file should fix it.

I am maintaining a fork of the material-color-utilities TypeScript library which aims to support best practices: a better file structure, better exports, using tsdown for bundling, ESM-only, aligning feature support with the Java library, etc.

There are a few breaking changes though: for example, union types were replaced with enums to align API design with other implementations of the library (Java serves as the reference implementation).

It is published on NPM under the name @materialx/material-color-utilities.
