Pull request overview

This PR upgrades TypeScript from version 4.9.5 to 5.9.3, a major version upgrade that brings the project up to date with the latest TypeScript release. The changes include necessary configuration adjustments and dependency updates to support the new TypeScript version.

Key Changes:

• Upgraded TypeScript from ^4.6.3 to ^5.9.3, a major version jump that improves type checking capabilities and language features
• Added skipLibCheck: true to tsconfig.json to optimize compilation by skipping type checking of declaration files in node_modules
• Simplified dependabot configuration by removing redundant grouping rules that overlapped with the catch-all dev-dependencies group
