patch: Mark `@urql/core` as a peer as well as a regular dependency

Context

Originally (I reckon during the introduction of @urql/core), we decided to only include @urql/core as a dependency, since it never is a direct dependency. This allowed it to install automatically and deduplicate as long as all ranges match.

This wasn't ever a problem assuming deduplication was working (which it sometimes isn't in Yarn Legacy). However, @urql/core is only actively instantiated once in any given app. This means that for all exchanges it's only used to share types.

Problems with this is though, @urql/core's types contain instances that TypeScript will always consider as incompatible if they're duplicated. This means that this approach stopped working for TypeScript.

Summary

While we could provide shared global namespace types in @urql/core, which is my alternative proposal to solve this, we can also mark all dependencies on @urql/core as peer dependencies now.

Generally, peer dependencies install automatically with all package managers these days. But to keep backwards compatibility we can also keep @urql/core in dependencies at the same time. This should simply prompt package managers to always deduplicate it.

This PR also removes the >= range on it (although it's perfectly safe, this allows us to revamp some APIs in the next major of @urql/core), and updates the graphql peer dependency

Set of changes

Update prepare script
Update @urql/core dependencies to also be accompanied by a peer dependency
Update @urql/core ranges to ^5.0.0
Update graphql ranges to ^15.0.0 || ^16.0.0 || ^17.0.0 (dropping 0.x ranges for peers)
- Not a breaking change, since the update is explicitly minor and support hasn't technically changed, so overriding this is safe
