Update Ace model to support Bokeh 3

[hoxbro]

Update the Ace model to support Bokeh 3, but some sizing problems still exist. Though I think these problems are more general than related to the Ace model.

1. stretch_both in a notebook (stretch_width works fine):
   
   
2. Widget exceeds Tabs width
   
3. Column does not respect the sizing_mode of Ace.

   import panel as pn
   
   pn.extension("ace")
   
   editor = pn.widgets.Ace(value="import sys", language="python", sizing_mode="stretch_width")
   pn.Row(editor).servable()  # Does not work
   pn.Row(editor, sizing_mode="stretch_width").servable()  # Does work
   editor.servable()  # Does work
