python39 py39-html-docs: updated to 3.9.9

Python 3.9.9 final

Core and Builtins
bpo-45738: Fix computation of error location for invalid continuation characters \ 
in the parser. Patch by Pablo Galindo.

Library
bpo-45235: Reverted an argparse bugfix that caused regression in the handling of \ 
default arguments for subparsers. This prevented leaf level arguments from \ 
taking precedence over root level arguments.
bpo-45765: In importlib.metadata, fix distribution discovery for an empty path.
bpo-45644: In-place JSON file formatting using python3 -m json.tool infile \ 
infile now works correctly, previously it left the file empty. Patch by Chris \ 
Wesseling.

Documentation
bpo-45772: socket.socket documentation is corrected to a class from a function.
bpo-45392: Update the docstring of the type built-in to remove a redundant line \ 
and to mention keyword arguments for the constructor.

Windows
bpo-45732: Updates bundled Tcl/Tk to 8.6.12.
bpo-45720: Internal reference to shlwapi.dll was dropped to help improve startup \ 
time. This DLL will no longer be loaded at the start of every Python process.
