Reference new Samba ports in the chapter about Samba services

[0mp]

Summary

The net/samba-smbclient port is no longer in ports. Replace it with
net/samba48. Also, mention net/samba48 instead of net/samba46.

Ah yes, this is a good low-hanging fruit. We have a lot of mentions specific versions in the handbook and I've often thought about generalizing them ("use the latest version from the Ports Collection") or writing some kind of tool that would report if there is a new version in ports available.

Anyway, approved for commit,
