Remove "FIXME" from translations

[lslezak]

Problem

• The Weblate translations contain the "[FIXME]" text

Solution

• As a quick fix to not confuse translators remove the string
• Later add some real label

Thanks @lslezak

I really sorry, I forgot yesterday about it because amount of work and I was not around this morning when you reminded it in IRC channel.

We will add meaningful aria-label, if really needed, in next iterations. If not needed, the attribute will be drop.
