Subject: [PATCH] fix: Mark react-native-nitro-modules peer dependency as
 optional

Semver ranges never match pre-releases, so a required peer of "*" does
not match e.g. 0.37.0-beta.0. Package managers then install a second,
stable copy of Nitro next to the pre-release, and the native/JS version
guard throws "Nitro was installed twice" at runtime.

Marking the peer optional leaves the consuming app in full control of
the installed Nitro version.
