chore(docs): Add MDX testing utilities

Add test:mdx script using @vendure-io/docs-provider/testing to validate
MDX files before publishing. This catches compilation errors early in
the development feedback loop.

- Add scripts/test-mdx.ts with testManifestMdx integration
- Add tsx dev dependency for running TypeScript scripts
- Update prepublishOnly to run MDX tests before build
