The array_hook parameter added to the JSON decoders in gh-146440 has version notes but no example, while the "Customizing JSON object decoding" section only shows object_hook and parse_float.

This adds two short examples there: one turning every JSON array into a tuple, and one pairing array_hook with object_pairs_hook to get a deeply immutable result, which is the use case the JSONDecoder docstring already describes. Both are marked # doctest: +SKIP, since the parameter needs Python 3.15 or later and the docs are often built with an older interpreter.

While there, it fixes a small wording slip in the array_hook parameter description ("decoded with as a Python list") and a typo ("structute") in the JSONDecoder docstring.

Documentation only, so there is no news entry.
