Fix: OpenAPI Schema for held_items

[PraaneshSelvaraj]

This PR updates the held_items schema in the PokemonDetail response to correctly reflect it as an array of objects (not a single object), matching actual API responses.

Fixes #1247

@PraaneshSelvaraj you'll also need to regenerate the spec to apply your changes. If I remember correctly running the command below should do it.

make openapi-generate

@Naramsim would it be a bad idea to add openapi instructions some where in the docs?

[PraaneshSelvaraj]

@Indyandie I regenerated openapi.yml. I only changed held_items, but a lot changed in the file. Did I do something wrong or was it just outdated?

[Indyandie]

There have been lots of updates since the last generation.

@Naramsim maybe we can add some automation to regenerate the spec anytime there are relevant changes.

@Indyandie Hey, Is this PR good to merge or should I add something else?

[Indyandie]

Your changes should fix the issue.

[PraaneshSelvaraj]

@Naramsim Hey, PR is good to merge now.
