fix: run example error in xcode

[Jamlee]

Summary

Under the current circumstances, Example cannot run because the files in AuroraEditorSourceEditor seem to have only been modified halfway, some are called AuroraEditorSourceEditorExample, and some are called CodeEditorSourceEditor. I changed the whole thing to AuroraEditorSourceEditorExample and it runs through on Xcode 15.

Changes Made

1. The Example directory compiles through as a whole.
2. The LanguagePicker in Example cannot echo back because CodeLanguage always defaults to false when compared.
3. textViewDidChange must be public

TODO

none

Motivation

Run the Example normally to understand more intuitively the principle of implementing an editor with SwiftUI

Testing

none
