fix: CocoaPods publishing workflow

The CocoaPods publishing has been failing due to two issues:

1. The pod-publish job had an overly restrictive condition that only
   allowed publishing from GitHub release events. When called from
   release-please via workflow_call, the event name is inherited as
   'push', causing the job to be skipped.

2. The workflow referenced ./scripts/update_podspec.sh which was deleted
   in commit 2903008 when release-please was configured to handle
   version updates automatically.

This commit fixes both issues by removing the unnecessary condition
(release-please already guards with release_created) and removing the
reference to the deleted script.
