Godot 4+(master) GDExtension C++ example instructions on macos not working

**Your Godot version:**

```
% git rev-parse HEAD

```

**Issue description:**

On MacOS gdexample.gdextension doesn't point to correct library:
```
ERROR: Can't open dynamic library: /Users/jpedrick/Development/godot-master-cpp-tutorial/cpp-tutorial/demo/bin/libgdexample.macos.framework, error: dlopen(/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework, 0x0002): tried: '/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework' (no such file), '/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework' (no such file).

```

Two fixes are needed:

1) scons platform=macos => scons platform=macos target=editor
2) gdexample.gdextension =>

```
[configuration]

entry_symbol = "example_library_init"

[libraries]

linux.64="res://bin/libgdexample.linux.64.so"
windows.x86_64="res://bin/libgdexample.windows.x86_64.dll"
macos="res://bin/libgdexample.macos.editor.framework/libgdexample.macos.editor"
```
