An error should be thrown when an undefined scene is started

[ubershmekel]

Version

• Phaser Version: v3.55.2

• Operating system: MacOS

• Browser: Chrome

Description

When starting a scene with an invalid key, the command just kills the current scene with no error shown.

https://github.com/photonstorm/phaser/blob/5c8ecbcf999e6f328d21884e877c9e5935d2d350/src/scene/SceneManager.js#L1154

Seems there is no handling of the negative case of that if.

Example Test Code

When no such scene was registered in the GameConfig:

this.scene.start("game-over");

Additional Information

Would a PR to console log/warn be considered?
