net: shaper: add a note that we expect cap dumps to be tiny

Browse Source 
Various AI scan tools may complain that we don't support resuming
the cap dump. This is true, but the cap dumps are tiny.
net_shaper_nl_cap_pre_dumpit() sets up the dump for just
one device, so the size of the dump scales with NET_SHAPER_SCOPE_MAX (3).

We don't expect them to ever need more than a 4kB page.
Document this.
