Fixes #39

This PR updates the ZendeskMessaging SDK to version 2.19.0.

To test this, I had to also update the React Native example project to latest as couldn't really start the project on Android (and it feels like it needed an update as well).

[!IMPORTANT]
The changes proposed within the example project are mostly coming from this tool.

[!NOTE]
No native code was changed

Testing

Manually testing using both the example project and a personal project. Messaging, notifications, callbacks, etc seem to be working fine

Other changes

• [x] some existing Kotlin linting errors appeared. Fixed automatically using ktlint
• [x] targetSdkVersion is now set to 33 due to the updated Kotlin version.

It think it's better to downgrade version to 2.18.0 #47

It would be nice having this repo updated to latest version (2.26.1) since version 2.22.0 introduces breaking changes. @mfds In your opinion, what are the steps to be able to update to version 2.26.1?

@matteomelotti not really sure but I might be able to tell you soon (maybe next week).

Anyway, what I can suggest you in general is to fork this project, remove the example app and upgrade the SDK following the maintainer instructions.

The example app is basically the bulk of this PR, update itself was a very easy process (so far).

Try it and see what breaks :)
