Now it is only required to provide one of Fabric: API Key (api_key) or GoogleService-Info.plist path (service_info_plist_path) to upload dSYMs to Crashlytics, Fabric: Build Secret is optional.
In case using Firebase Crashlytics: to keep your historic crash data, provide your Fabric API key if you have migrated this app to Firebase. If you onboarded this app via Firebase provide GoogleService-Info.plist path.
Same to the previous releases set IPA file path (ipa_path) to empty string to only upload dSYMs, and skip Fabric Crashlytics Beta deploy feature.
Updated upload-symbols binary used to upload dSYMs.
