continuous-deploy-fingerprint: Support platform: ios,android to exclude web from eas update

[MaganAnkur]

Description of the bug

The continuous-deploy-fingerprint action's platform input only accepts 'all' | 'ios' | 'android'. When set to all (the default), builds are correctly scoped to iOS + Android, but the eas update step runs eas update --platform all, which triggers expo export for all platforms including web.

This causes failures for projects that use native-only modules (e.g. react-native-fast-tflite) which crash during the web export phase:

Metro error: Cannot read properties of undefined (reading 'getEnforcing')
TypeError: Cannot read properties of undefined (reading 'getEnforcing')

Expected behavior

is there any way to target both native platforms without including web. For example:

Accept comma-separated values: platform: ios,android
Or add a new option like platform: native
Or pass --platform per-platform to eas update the same way builds already resolve all → ['ios', 'android']

Actual behavior

• platform: all → builds for iOS + Android (correct), but eas update --platform all exports for web too (breaks)
• platform: ios → only handles iOS
• platform: android → only handles Android
• No option to target both iOS and Android without web
  Running the action twice (once per platform) is not viable because the second invocation overwrites the first PR comment (same messageId).
