Minor Errata in CS3223 Finals Cheatsheet

[Devanshshah1309]

The definition of "covering index" should be changed from:

if all attributes referenced in $Q$ are part of the key of $I$

to:

if all attributes referenced in $Q$ are part of the key or include columns of $I$

But doing so results in exceeding the one-page limit - so, I'm not sure if you want to make this change + remove one line from somewhere/reduce the font size by a bit/something else, or ignore this altogethr.

P.S. your cheatsheets have been incredibly useful 🙏 thanks a lot for them!
