fix: caching the opensea response causing the TypeError when deserializing

[crnkovic]

Summary

https://app.clickup.com/t/86drgahvk

The problem is that we used to cache the entire OpenSea response, which is serialized and put into Redis, then deserialized. It can't properly be deserialized, and thus failed. We can cache the JSON response, though. That can be serialized with no issues.

As a bonus, I inlined the OpenSea API URL and the version as there is no more v1.

What we did:

Cache::remember('key', $ttl, fn () => Http::get('/some-endpoint'));

What we need to do:

Cache::remember('key', $ttl, fn () => Http::get('/some-endpoint')->json());

When testing and after deployment, please clear cache: php artisan cache:clear

To test, set cache driver to redis, open tinker, and run the following code twice Opensea::getCollectionFloorPrice('proof-moonbirds').

> Opensea::getCollectionFloorPrice('test')

   TypeError  fseek(): Argument #1 ($stream) must be of type resource, int given.

Clear cache and try again after this PR.
