[PATCH installer] tui: network: toggle form labels too in advanced options dialog

[Christoph Heiss <c.heiss@proxmox.com>]

This follows the GUI more closely by also changing the style of the
labels to make them the same coloring as disabled interactive form
elements.

Suggested-by: Lukas Sichert <l.sichert@proxmox.com>

Just a small follow-up patch for the series, w/o the need to re-spin it
all.

Can also rebase & resend to whole series with this patch properly
integrated, if wanted so.
