[PATCH] ci: update Cirrus-CI image to FreeBSD 13.0

[Philippe Blain <levraiphilippeblain@gmail.com>]

The FreeBSD CI build (on Cirrus-CI) has been failing in
't9001-send-email.sh' for quite some time, with an error from the
runtime linker relating to the Perl installation:

    ld-elf.so.1: /usr/local/lib/perl5/5.32/mach/CORE/libperl.so.5.32: Undefined symbol "strerror_l@FBSD_1.6"

The first instance is in t9001.6 but it fails similarly in several tests
in this file.

The FreeBSD image we use is FreeBSD 12.2, which is unsupported since
March 31st, 2022 [1]. Switching to a supported version, 13.0,
makes this error disappear [2].

Change the image we use to FreeBSD 13.0.
