Please use the latest version of lintian

Hello,

As reported on https://bugs.debian.org/1003340 , https://lintian.debian.org/ lintian runs, which end up showing up on our QA pages, are using the latest version of lintian from the git tree itself. Whenever the lintian output changes, we have to update suppression rules in the overrides files. But if the lintian.debian.org runs and the salsa CI are not using the same version, we end up having a red flag on one of them anyway.

Could we make the Salsa CI automatically use the latest git version of lintian, to be in sync with lintian.debian.org?
