fix: Add types of GroupChat and OpenChat for SendbirdChat (#518)

### Description Of Changes

Issue
* Customer had to use the type assertion for removing type error
```javascript
const globalState = useSendbirdStateContext()
const getSdk = sendbirdSelectors.getSdk(globalState) as SendbirdGroupChat;
getSdk.groupChannel.getTotalUnreadMessageCount();
```

Fix
* Specify the `getSdk` returns SendbirdGroupChat or SendbirdOpenChat
