nice work, works flawless, thank you!
Just 2 minor suggestions:
in your documentation you suggest to name the filter = symfony in the jail.local. Since you also suggest to name the Kimai specific filter #/etc/fail2ban/filter.d/kimai2.conf (and not symfony.conf), the filter name has to be filter = kimai2 in the jail.local
it would be nice to have some hint about the plugin being installed even though there are no options to configure it within Kimai
