[Python 3.11 only] "Post-init processing" section of dataclasses contains duplicate sentences + malformatted code example

Documentation

NOTE: Python 3.11 Docs Only

Issue:

The "Post-init processing" section of dataclasses in the Python 3.11 documentation contains duplicate sentences and a malformed code example. These issues aren't in the other active Python versions (i.e. 3.9, 3.10, 3.12, 3.13)

Proposed Fix:

The fix is to replace the 3.11 "Post-init processing" section with that of the 3.12 branch, which doesn't contain the duplicate sentences or bad formatting. To my knowledge, there are no new features added in 3.12 that makes this section incompatible with the 3.11 documentation, so it's safe to use it.
