guix hash: Allow '-r' as a non-deprecated alias.

Browse Source 
This is a followup to 05c962594c346da21f201be72caadfa19060cc9d.

Discussed at <https://issues.guix.gnu.org/51307#24>.

* guix/scripts/hash.scm (%options): Warn about deprecation for
"--recursive", but not for '-r' as it's a convenient shorthand.  Mention
'--serializer=nar' in the deprecation message.
* doc/guix.texi (Invoking guix hash): Adjust accordingly.
