[hossam-nasr]

Once #475 is fixed, let's upgrade the Durable upgrade guide for v4 programming model to simplify sections on types and API updates. Specifically:

• Update the table of API updates: https://github.com/MicrosoftDocs/azure-docs-pr/pull/233725#discussion_r1167305061
• Update the list of new TypeScript types: https://github.com/MicrosoftDocs/azure-docs-pr/pull/233725#discussion_r1161972705
