Consider updating deprecation columns

[duncandewhurst]

Currently, we have have:

• Deprecated: The minor version (or patch version under 0.x) in which the code was deprecated.
• Deprecation note: The reason for the deprecation, and any guidance.

We could considering mirroring the approach used in the JSON Schema Extension:

• Deprecated: Whether the code is deprecated (boolean)
• Deprecated version: The minor version (or patch version under 0.x) in which the code was deprecated.
• Deprecation details: The reason for the code’s deprecation and information about its replacement, if any.
