Automatically detect Release name and version for Expo Web

[krystofwoldrich]

On mobile release is automatically prefilled based on the native application metadata, package@version+build (for example, [email protected]+1234).

On web, release is expected to be set manually by the user. Since Expo Web project contain metadata about the project name and version, we can match the behavior from mobile and fill in release based on the ExpoConfig.
