Locale for Hungary updated!

The locale Hungary (hu-HU) was updated for 2022.

The holidays according to the decree on the work schedule around the 2022 public holidays (rendelet a 2022. évi munkaszüneti napok körüli munkarendről) have been added.

Additionally, we fixed an error in the notes for the swapped holidays. They now refer correctly to the corresponding Saturday as ‘working day’ ('munkanap').
