MacOS Sonoma 14.4: `airport` tool is removed and script can't get wi-fi SSID

The /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport tool is marked as deprecated and was removed from the MacOS 14.4.
Instead of it the wdutil has to be used.
I'm going to create a PR with the replacement and some refactoring.

Actually, no need to create a new PR, as we already have everything we need in the #30. I've tested it and it works fine.
