bug: `@react-native/polyfills/error-guard.js` not transpiled in distrobution

Description

In trying to integrate @swc/jest into our React Native codebase - it was discovered that one of the files (error-guard) was not being transpiled correctly. I’m not sure if this is by design or not - but the sibling files do not have types. So my guess is that this is not intended.

Is it possible to have an update on this? Our repository suffer with jest and supporting @swc/jest for testing would be really cool.
