Description:

The docstring for the themes property in the ThemeRegistrationAny | StringLiteralUnion<Themes> type currently references a non-existent URL:

/**
 * @see https://github.com/shikijs/shiki#lightdark-dual-themes
 */
themes: Partial<Record<string, ThemeRegistrationAny | StringLiteralUnion<Themes>>>

However, the link https://github.com/shikijs/shiki#lightdark-dual-themes is broken because the section is not existed in README.

Source:
options.ts Line 83

Suggestion:

• Update the docstring with the correct link to the documentation for dual theme support.
• If the documentation has moved or been removed, consider adding a short inline explanation or pointing to the relevant usage example or README section.

Thanks!
