Title: doc: colorize deprecated api notes

API stability notes are very easy to overlook since they are the same
color as other code snippets. Likewise, deprecated and non deprecated
api look the same and give no visual feedback (other than a number
change) that one should not use the particular api. Using red for the
outline of deprecated api notes brings attention to the fact they are
deprecated.
