lang/php72: Update from 7.2.22 to 7.2.23

The last log entry is the same, because i accidently performed an update from
7.2.21 to 7.2.22. I ignored the update to 7.2.22 because for FreeBSD its a no-op.
But when 7.2.23 was released i only increased the version by one.
This time its the real update! :)

Changelog:

Core:
    Fixed bug #79877 (getimagesize function silently truncates after a null byte) (cmb)
Phar:
    Fixed bug #79797 (Use of freed hash key in the phar_parse_zipfile function). (CVE-2020-7068)
