[JOSS] Update paper.md

I figured it's easier to fix with PR, since it's just a small typo/weird wording.

 DREiMac adds to the current landscape of cohomological coordinates software by implementing various currently missing functionalities; we elaborate on these below.
 DREiMac also includes functions for generating topologically interesting datasets for testing, various geometrical utilities including functions for manipulating the coordinates returned by the algorithms, and several example notebooks including notebooks illustrating the effect of each of the main parameters of the algorithms.
