refactor: Update snort.ps1 to install Snort, Npcap, and WinPcap

This commit refactors the `Install-Snort` function in `snort.ps1` to include the installation of both Npcap and WinPcap. Previously, only Npcap was installed, but now WinPcap is also downloaded and installed using the provided URLs. The environment variables are updated to include the path to the WinPcap installation directory. This change ensures that both Npcap and WinPcap are properly installed and configured for Snort to function correctly.

Refactor the `Install-Snort` function in `snort.ps1` to install Snort, Npcap, and WinPcap
