Argparse docs have a strange fragment identifier for `name or flags`

Bug report

Bug description:

Clicking on the "name or flags" parameter under the add_argument method docs links to #id5 instead of #name-or-flags. The jump target isn't broken, but it has a slightly worse UX. It looks like this behaviour changed from the 3.11 docs onward.

CPython versions tested on:

3.12, 3.13, CPython main branch

Operating systems tested on:

macOS
