Update datatypes to match recent release of plugin

I made changes to cordova-plugin-health to accept the following array as datatypes. Earlier it was just an array of strings. Now it also contains an object with `read` and `write` array.

```
[
  'calories', 'distance',   //read and write permissions
  {
    read : ['steps'],       //read only permission
    write : ['height', 'weight']  //write only permission
  }
]
```

Don't know how to specify this array in typescript so just replaced by 'any'
