Updated the Download function to attempt to retry the download upon an error for at least 3 times.

Updated the downloadFile function in PackageManager.php to retry the download upon an error for at least 3 times. This improvement on error handling will enhance the resilience of the download process, reducing the likelihood of a single network hiccup resulting in a failed download. This change has also been reflected in the CHANGELOG.md file.
