Update gulp

[vrdmr]

This pull request refactors several Gulp tasks in Build/gulpfile.js to improve error handling and compatibility with newer Gulp versions. It replaces deprecated modules, updates dependencies, and ensures asynchronous tasks handle empty input gracefully. The changes are mainly focused on modernizing the build process and making it more robust.

Dependency and Module Updates

• Replaced the deprecated request module with Node's built-in https for downloading files, and updated task implementation to handle download errors and file cleanup (gulpfile.js, package.json). [1] [2] [3]
• Updated the gulp dependency from version 4 to 5 in package.json for improved compatibility and future-proofing.

Task Error Handling and Asynchronous Flow

• Refactored multiple Gulp tasks (unzip-templates, resources-convert, resources-build, resources-copy, userprompt-copy, zip-output) to accept a done callback and return early when there is no work to do, preventing hanging or unnecessary execution. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Minor Task Callback Consistency

• Ensured callbacks (cb) are called at the correct locations in build-templates and build-templates-v2 tasks to maintain consistent asynchronous behavior. [1] [2]
