Extension ID renaming plan

[jcheng5]

In mid-May (when Joe gets back from vacation):

• Publish new extension under Posit.shiny
• Simultaneously, publish new version of Posit.shiny-python that removes all contribution points and depends on Posit.shiny, and rename to "[Deprecated] ..."
• Unpublish the very old, long-deprecated rstudio.pyshiny so we don't have two deprecated extensions showing up in search
• Review usage of Posit.shiny-python and PR the name change (e.g. Posit.shiny-python is a recommended extension in py-shiny)

A good outline of the process: microsoft/vscode#59918 (comment)

Apparently we can also add a note in this thread for an official deprecation notice in the extension marketplace microsoft/vscode-discussions#1

This seems to be effective only for marketplace.visualstudio.com, I can't find a way to rename or remove an extension on open-vsx.org.
