- fixes CocoaPods publishing by correcting release-please workflow
outputs which were causing publication to be skipped
- removes incorrect namespace prefix from workflow outputs
(`OpenFeature--release_created` → `release_created`)
- updates comment to align with behavior for simple release type with
root path

Fixes #91

### Notes
<!-- any additional notes for this PR -->

The workflow was incorrectly using namespaced outputs like
`steps.release.outputs['OpenFeature--release_created']`, but the simple
release type with root path (`.`) doesn't actually namespace outputs.
This caused the CocoaPods job condition to evaluate to false, skipping
publication.

Verified by examining workflow logs from the 0.5.0 release which show
actual outputs are `release_created`, `version`, etc. without namespace
prefixes.
