Clean up for 5/19/2022 content update

[Gregory Hecht]

This week's update added the book title She-Hulk Goes to Murderworld: A Marvel: Multiverse Missions Adventure Gamebook.  Is that title punctuated correctly?  

The comic book title Big Nate: Very Fiunny! was added.  That should of course be spelled as Big Nate: Very Funny!   

The title Spider-Man's Greatest Team-Ups was added.  Based on the date, price, and cover scan, this looks to be a duplication of Spider-Man: His Greatest Team-Up Battles.  I don't know which of the two titles is correct, but I think that one of them needs to go.  

The following issues were added to the title Snowpiercer:  #4, #4/HC, #5, and #5/HC. 
•  #4/HC and #5/HC are duplications of the already cataloged Snowpiercer The Prequel comics.  Those books don't have a vol. 4 or a vol. 5 on them anywhere (not on the cover, the spine, nor the indicia) and their title on the indicia page is indeed Snowpiercer The Prequel.  So for sure the new #4/HC and #5/HC entries for the Snowpiercer title should be deleted.  
•  I assume that #4 and #5 are trade paperback versions of the two Snowpiercer The Prequel hardcovers.  However, I don't have those so I cannot verify whether their indicia states "Snowpiercer" or something else, nor whether they bear the volume numbers of 4 and 5 anywhere.  It would seem to me that this info would clarify where the issues that were added as #4 and #5 should be cataloged.
