I'm releasing extra packages than necessary just so people can more easily can bump the thing they directly depend on rather than refreshing whole lock files.

Fixes #3222
Arguably this isn't really a bug in Emotion since tools like Next should use the conditions on external code correctly (it works correctly with the App Router since they bundle everything) but the reality is like this and the fix makes it less complex anyway imo.
This will sort of "break" source maps in older versions of the babel plugin with new versions of the runtime and vice versa but since it's only breaking source maps, I think that's fine.
Also, I checked the swc emotion plugin and it doesn't seem to do the particular optimisations that the Babel plugin does so it doesn't need to change.
