Fix modulemap typo (facebook#41564)

Summary:

X-link: facebook/yoga#1474

Fixes facebook/yoga#1468

We build with Swift, but don't build something consuming Yoga module, and don't use modulemap and CocoaPods. This is a gap in validation we should figure out, but in the meantime, we should fix the typo.
