fix(expo): add Kotlin metadata version skip to app.plugin.js

The previous commit only updated src/plugin/withClerkExpo.ts, but Expo
uses app.plugin.js (the hand-written CommonJS file) at runtime. This
adds the -Xskip-metadata-version-check flag to the actual plugin file
that gets shipped and executed during prebuild.
