{CI} Ignore downloadUrl when comparing index.json entries and always run service_name check (#9358)

- Add entry_equals_ignore_url to detect modified index.json entries while ignoring downloadUrl differences (avoids treating URL-only changes as metadata changes).
- Replace direct entry inequality with URL-agnostic comparison to build correct modified_entries list.
- Remove special-case skip for 'deploy-to-azure' so service_name.check runs for all external extensions.
