bug: Derive macro without explicit import.

The derive macro `GetTypeDependencies` required the `bevy_mod_scripting_core`
to be an explicit dependency. I altered it to refer to
`::bevy_mod_scripting::core` instead of `bevy_mod_scripting_core` so
that it works with the usual dependency of `bevy_mod_scripting`.
