Enable Salsa CI using default template

I noticed this package is uninstallable in Debian experimental:

Unpacking cracklib-runtime (2.10.2-0.1+b1) ...
dpkg: error processing archive /tmp/apt-dpkg-install-IFPJak/14-cracklib-runtime_2.10.2-0.1+b1_amd64.deb (--unpack):
 trying to overwrite '/usr/share/man/man8/cracklib-check.8.gz', which is also in package libcrack2:amd64 (2.10.2-0.1+b1)

This type of error would have been automatically detected by Salsa CI (and/or deb-check-file-conflicts). Hence suggesting pacakge to adopt Salsa CI.

This MR is targeting the master branch, but a copy of it on the experimental branch fails on multiple jobs as visible in https://salsa.debian.org/debian/pkg-cracklib/-/pipelines/932142

They all reveal the problem and if this package had Salsa CI those problems would be detected prior to upload:

badpkg: Test dependencies are unsatisfiable. A common reason is that your testbed is out of date with respect to the archive, and you need to use a current testbed or run apt-get update or use -U.

I am not planning to do a second MR with the same change, and for now only have this improvement suggestion targeting the master branch which is the default branch in this repository.
