WezTerm.app/Contents/Info.plist: request network permissions

On MacOS 15 (Sequoia) and later,
Wezterm.app should ask for a LocalNetwork entitlement by default.

This fixes mysterious network failures (eg: 'no route to host') when:

- Wezterm is a toplevel process (ie: not a child of a process
  that already has LocalNetwork entitlement, like Terminal)
- A shell running inside Wezterm executes a process which accesses the network,
  but does not itself already have a LocalNetwork entitlement,
  eg: /etc/profiles/per-user/$(whoami)/bin/ssh
  for ssh installed by nix home-manager.
