dhcpcd and wpa_supplicant

The network section main page has a section "dhcpcd". IMO, this should be moved out into a subpage just like the rest of the network handlers are.

In addition, when I set up my most recent void system, I had trouble linking wpa_supplicant with dhcpcd and just relied on my other system's configuration to make sure I got it right.

It requires either the linking or copying 10-wpa_supplicant to /usr/libexec/dhcpcd-hooks from /usr/share/dhcpcd/hooks. I believe this is void-specific and belongs in the handbook, especially given that void has dhcpcd enabled by default. This is in Arch's Wiki (https://wiki.archlinux.org/index.php/Dhcpcd#10-wpa_supplicant) but has different paths to void.

Repérez la page principale de la section réseau et les sous-pages existantes consacrées aux gestionnaires réseau, puis examinez l’organisation de la section dhcpcd. Vérifiez la relation entre /usr/share/dhcpcd/hooks/10-wpa_supplicant et /usr/libexec/dhcpcd-hooks, et utilisez la référence de l’Arch Wiki comme contexte. Le travail est terminé lorsque dhcpcd dispose de sa propre sous-page et que la configuration de wpa_supplicant spécifique à Void est documentée.
