[DX-3465] feat: update uwb

[nattb8]

Summary

Passport package

• Update UnityWebBrowser (UWB). Everything in src/Packages/Passport/Runtime/ThirdParty/UnityWebBrowser is straight from UWB v2.2.5 version. Only two changes have been made:
  • Added the ability to turn off sandbox.
  • Skip the PixelDataLoop so it can be headless.
• Updated game bridge file to include new callback function for UWB.

Sample app

• Added a launch browser scene to showcase how to use UWB to load a web page.

Tests

• Updated test account
• I commented out the register off-chain UI test case for now as the Passport throws a server error.

Other things to consider:

• Sample app is updated with new SDK changes

This and v1.30.1 seem to try to instantiate the weird bundled unity browser incorrectly, via new().
This is not allowed for ScriptableObjects or MonoBehaviours, these must be created with the appropriate factory methods (or imported as assets).
