Simple PDF documentations for star battle boards that aren't visually clear

[offline171]

Description

Just include pdf files of some of the region board states for star battle as currently, they lack these in the program itself

Type of change

• Enhancement (improvement to an already existing feature)

How Has This Been Tested?

I tested this by having LEGUP open the file, which gave a simple error message, then letting me choose the correct puzzle. To stop people from choosing the pdf files instead of the actual puzzle files, I labeled the pdfs so as to make it clear to not open them as a puzzle
