Update subproject commit reference and enhance GitHub workflows

- Updated the subproject commit reference in the skills directory.
- Modified the build workflow to enable submodule fetching.
- Standardized quotation styles in the package-and-publish workflow for consistency.
- Refactored the `setSkillOAuthCredential` function for improved readability.
- Added an attribute to the `Error` variant in the `SkillMessage` enum to suppress warnings for unused code.
