refactor: Remove WinPcap installation from Install-Snort function

The `Install-Snort` function in `snort.ps1` is refactored to remove the installation of WinPcap. Previously, both Npcap and WinPcap were installed, but now only Npcap is downloaded and installed using the provided URL. This change ensures that Npcap is properly installed and configured for Snort to function correctly.
