[UX] Wheel files filter issue with free-threading builds

[cdce8p]

Describe the bug
#15087 added the option to filter the wheel list. It's a great feature and I've already used it a couple of times since to check which specific wheels are available.

I've one minor annoyance though. The ABI filter includes entries for "standard" and "free-threading" builds, e.g. cp314 and cp314t. However, selecting cp314 still shows the cp314t wheels as well. I'd have expected those to be filtered out and only show up when I actually select cp314t.

Expected behavior

To Reproduce

An example can be seen on the downloads page for https://pypi.org/project/aiohttp/#files or any other project which has published dedicated free-threading wheels.

The ABI filter list both cp314 and cp314t separately

Selecting cp314 shows both cp314 and cp314t wheels

For cp314t it's just the one I'd expect
