Expose errors and metadata types

[ewanharris]

The frontend-utils package currently imports all errors via the dist folder. We don't really want that as we shouldn't encourage importing through dist.

Instead make this exported fully and also ensure that the types are fully up to date (e.g. typeName and relation here)

👋🏻 @JanumalaAkhilendra I've assigned this issue to you, we'd like to make the errors that you see here exported from the JS package in this repo.

If you need any assistance please feel free to ping me.
