Fixed typo on Releeph product query dropdown.

Summary:
Changed "Active Prodcuts" to "Active Products" on Releeph Product Query dropdown.

(Incidentally, this is my first diff on Phabricator proper, so I hope I got it right. I'm used to SVN, not Git.)

Test Plan: Make sure the change is there and didn't bork anything else.
