PR: Implement wget installation and usage for file downloads

Changes

This PR implements the installation and usage of wget for file downloads across different operating systems. It also refactors the existing download function to use wget instead of the previous implementation.

Key Updates:

1. cmd/install.go:

   • Added a new function installWget(ctx context.Context) to handle wget installation across different operating systems (Linux, macOS, Windows).
   • For Windows, it includes a check for Chocolatey and installs it if not present.
   • The function is called before certain installation processes to ensure wget is available.

2. utils/utils.go:

   • Refactored the DownloadFile function to use wget instead of the previous Go implementation.
   • Removed the custom progress reporting in favor of wget's built-in progress output.

Testing

The changes have been tested and verified on the following scenarios:

• Install and update commands on Linux
• Install and update commands on macOS
• Install and update commands on Windows (with and without Chocolatey pre-installed)
