Update .pr server to whois.nic.pr

Separate from rfc1036#176 as this
one is a bit less clear-cut. The IANA info still lists
whois.afilias-srs.net . However, as explained in rfc1036#176, Afilias
was bought in 2020 and the successor organization is named
Identity Digital; they have already let one Afilias domain which
hosted a whois server lapse (see rfc1036#177) so the chances of this
happening again seem non-zero, and it may be wise to change this.

whois.nic.pr , following the pretty common convention that a lot
of other TLDs use, is set up and points to the same Identity
Digital catch-all server that whois.afilias-srs.net currently
points to, so it seems like a sensible choice (and one that the
maintainer of the .pr TLD cannot lose control over).
