doc: network: Add default ctrl_interface and related parameters to wpa_supplicant.conf

[TheRealKraytonian]

This commit adds the following default configuration parameters to the example wpa_supplicant.conf in the handbook:

ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
ap_scan=1
fast_reauth=1

This is necessary for users to effectively disable, debug, and manage their wireless network connections. These parameters are already present in the example configuration files provided with wpa_supplicant, suggesting they are commonly used and beneficial for a standard setup. Including them in the handbook's basic example will provide a more robust and user-friendly default configuration for wireless networking.

A better commit message might be:

Handbook/network: Mention wpa_supplicant.conf boilerplate

Mention wpa_supplicant.conf boilerplate required for the wpa_cli wireless network manager. These parameters are already present in the share/examples/wpa_supplicant.conf.

Key points:

• handbook/network shows what is actually changing
• keep commit message titles terse for one line, many git tools limit to 50 characters
• no need to mention what, they can see that, the commit message needs to explain why
• check that path, I'm on my phone at work
• never say you tested something you authored, this is expected and required
• discussed with xor reviewed by, in this case, we talked about it but I hadn't seen a diff until just now
• you need to use your real name when changing global critical infrastructure

Edit: also please wrap the commit message at 72 columns.

Edit2: committers are just referenced by their username, but we're trying to demonstrate the impact of community discord by mentioning it in the log using the syntax I just provided.
