Update the ".pot"-file in this repository automatically

The ".pot"-file in this repository is outdated by a few versions, and thus does not include some of the most recently added translatable strings.
While an updated ".pot"-file is created with every CI-run in the main Cemu-repository, it is not uploaded to this repository automatically.
Automatically updating it here would make it easier to make translations of new translatable strings soon after they have been added to Cemu.
