feat: use pickup as CLUSTER_API_URL (#2179)

Update `CLUSTER_API_URL` in wrangler.toml to have the api use pickup in
place of cluster for handling pinning service requests.

The prod pickup is currently configured to proxy all requests back over
to cluster. The plan is to get pickup in the loop so we can control what
fraction of requests it should handle from pickyup config.

Note: Merging this PR will trigger a staging deployment, which will
apply the change to the staging config. Merging the release-please PR
will trigger a prod deploy and the prod config change will be applied
then.

TODO
- [ ] update `CLUSTER_API_URL` secret on repo so cron-pins uses the same
endpoint as the web3.storage api worker.
- [x] implement handler in pickup for `GET /pins?cids=baf1,...,bafN`
