Refactor expectTokenKind's return value to keep consistent with expectKeyword

[git-hulk]

This PR only changes the internal behavior and won't affect the parsed output.

[Copilot]

Pull Request Overview

This PR refactors the usage of expectTokenKind by removing its unused token return value to achieve consistency with expectKeyword, while keeping the parser’s behavior unchanged.

• Replaces constructs returning token and error with error-only returns in expectTokenKind calls.
• Updates all affected parser functions across multiple files to adapt to the new return signature.
