Description
This PR adds support for the embeddedLanguages field in LanguageRegistration.
Historically the field was named embeddedLangs, while VSCode grammars use embeddedLanguages.
Shiki currently supports only embeddedLangs, which prevents grammars using the VSCode naming convention from working as expected.
Linked Issues
Fixes #1044
Additional context
No breaking changes introduced — if both fields are present, embeddedLanguages takes priority.
This brings Shiki in line with VSCode terminology while preserving support for older grammars.
