Small improvements to Citra translations (#7379)

* dist: Remove duplicated Finnish translation

For some reason, we had Finnish listed twice on Transifex, causing it be shown twice in Citra.
It has already been deleted again from Transifex, now we only need to remove it from the repo as well.

* citra_qt/configure_ui: Show country of language in the combobox

This prevents an issue where we had seperate versions of the same language for different regions and they were not distinguishable (e.g. "Chinese (China)" and "Chinese (Taiwan)").
