Enhance GitHub workflows and templates

- Updated dependabot configuration to include Maven, GitHub Actions, and npm with weekly update schedules and limits on open pull requests.
- Added a pull request template to standardize contributions and ensure necessary information is provided.
- Introduced issue templates for bug reports and feature requests to streamline issue tracking and enhance user experience.
- Created workflows for CodeQL analysis, pre-commit checks, and stale issue management to improve code quality and maintainability.
