fix(core): make metadata available in production

[alpavlove]

Fixes #3715

Summary

This change addresses a bug where the addMetadata function was being stripped or modified in production builds, resulting in the meta field being unavailable. The absence of meta caused inconsistent behaviour between development and production environments, particularly for TTL-based re-requests and cache outcomes.

Previously, there was an attempt to add back the meta to production bundles, but perhaps the babel file was missed.

Set of Changes

Modified Babel Transformer:

Updated the Babel transformer to preserve addMetadata calls in production, ensuring metadata (e.g., cacheOutcome) is always available.

Affected Package:

@urql/core: The core package was updated to fix the issue.

@isy @JoviDeCroock any chance you guys could review this please?

[JoviDeCroock]

@redroot we remove the meta for a reason, it's meant to be for development - a better solution here might be to move it away from development metadata or for us to split up metadata in dev and not dev.

EDIT: I looked deeper into the few places where this transform is used and yeah, we should remove it entirely

It seems I can not merge myself due to a lack of permissions. Could you do it, @JoviDeCroock?

[JoviDeCroock]

@alpavlove That's normal yes, you are not a collab/member

@JoviDeCroock, unfortunately, it can't be released due to an error on CI
