✏️ Fix reversion in model_dump attribute handling for pydantic v2.7 .. v2.10

  + The else block added to fix linting errors (4b5ad42) for #1340 was
    obliterating the 'context' and 'serialize_as_any' attributes for
    versions >= 2.7 and < 2.11.
  + Fix by initializing extra_kwargs and then setting on a per-version level
