gitr: Ensure gettext is installed on Fedora 41

I'm getting the infamous "tclsh failed; using unoptimized loading"
error when building git on Fedora 41. I found that even though the
package list includes "gettext", the gettext package is not getting
installed.

StackOverflow says grabbing the "intltool" package will ensure that
"gettext" and "gettext-devel" will be pulled in.
