Fix health connect on activity result

[nektar95]

Problem:

When you have only installed Health Connect you cannot retrieve data from it using health plugin.

Solution: Request code for health connect wasn't checked so we couldn't proceed further with permission granted.

Hello, in order to comply with Android 14, we will update requestAuthorizationHC and as part of that eliminate the need to use startActivityForResult. Please see if your issue persists in the dev branch: https://github.com/cph-cachet/flutter-plugins/tree/health-dev.
