[issue42194] Docs for argparse.BooleanOptionalAction missing "New in version 3.9"

Am inclined to merge the former PR because yours is just an exact replica.

Please note that we can merge such small fixes without the author signing the CLA but the author is advised to sign the CLA for future contributions.

Source: informed by other core devs on reviewing similar PRs recently and a similar discussion was on a ML some time back.
