Fix/better url scheme check

[BellringerQuinn]

When building, check SequenceConfig for the url scheme; if set and if it contains uppercase characters, log a warning and open the warning popup window (as these logs may get cleared during the build process) warning the user that using uppercase letters may cause issues with deep linking on some platforms (e.g. while it works on MacOS, it doesn't work on Android)

• No version increment is needed; the change does not impact SDK or Sample code/assets

Docs Checklist
