docs(registry): fix incorrect GET tool documentation

- Update COLLECTION_REGISTRY_APP_GET docs to reflect actual behavior
- GET always returns LATEST version (is_latest: true)
- Version suffix in 'name@version' is accepted but IGNORED
- Remove misleading reference to GET supporting specific versions
- Clarify that COLLECTION_REGISTRY_APP_VERSIONS should be used for version queries

The implementation was correct, only the documentation was inaccurate.
