Typo in /var/ipfire/langs/en.pl

I was just poking around in Bugzilla and noticed this old bug I had created. https://bugzilla.ipfire.org/show_bug.cgi?id=10595

Basically, it causes the names displayed for the Root and Host certificates on the IPSec page to have inconsistent capitalization ("Host Certificate" vs. "Root certificate").

This is clearly not a big issue, but it's also an easy fix, and I thought "hey, I can fix this!" However, I'm not really certain what the best method would be to submit the change.

Any suggestions as to where I can start?
