Small fix for gdb/libpython.py docs

[Andrej730]

Just accidentally noticed that it was mentioning PyIntObject * type which is deprecated - replaced it with PyLongObject *. Also replaced "ob_ival" with "long_value" - similar field that's used in PyLongObjectPtr.proxyval.

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.
