chore(Authoring): Move model selection in AI Chat from advanced to basic editing view

[Aaron-Detre]

Changes

• Moved AI Chat model selection from advanced to basic authoring.

Test

• Model selection should be in basic authoring for AI Chat components.
• Model selection should not be in advanced authoring.
• Make sure model selection still works. After changing the model in authoring, requests should be sent to the new model.

Closes #2323
