Fixed the lack of italian language for player.

@Zvonimir-FUTO I don't know how to effectively add the Italian language to the player, except by creating a link inside the strings.xml. I'm assuming there's another source file to modify for the PR completion, but its name is unknown to me at the moment.

Let me know about this, if possible.

As far as I can see, none of the audio tracks and subtitles strings are translated... I suppose this classifies as a bug?

Because the italian language missing for the player I suppose. This PR should fix the issue...at least I hope.

This doesn't actually fix anything. Closed in favor of https://gitlab.futo.org/videostreaming/grayjay/-/commit/cfeceabe5bbd1240733ad8790afcda61ec2d655a
