Currently in `MenuMainBarView.axaml` we list all available languages and hardcode the language name with the language key.
It's a bit bad beause if we want to add a new language, we have to edit the `csproj` and the `axaml` with the translated language name and the language code.
I've put all translations in their respective locale files, add code into `MainMenuBarView` constructor to generate the menu automatically. Now we just have to edit the `csproj` if we want to add a new language.
`MB` and `GB` can either be interpreted as having base-10 units, or
base-2. `MiB` and `GiB` removes this discrepancy so that units of memory
are always interpreted using base-2 units.
* Add new string
You need the period there otherwise it could be read as "Głoś" -> "Preach"
* Update MainWindow.axaml
Updating to bring it in line with the other languages naming themselves in their respective languages
* Update pl_PL.json
realizing that period isn't necessary considering the string's usage (which to be fair, I should have checked when I added it)
* Update pl_PL.json
* Add Updater Message
