`mise install -f "pipx:*"` not working with latest mise

Discussed in #4146

With mise v2025.1.8, mise install -f "pipx:*" as described here to upgrade all pipx packages after a Python upgrade does not work (don't know if it ever has):

> mise install -f "pipx:*"
mise ERROR HTTP status client error (404 Not Found) for url (https://pypi.org/pypi/*/json)
mise ERROR Run with --verbose or MISE_VERBOSE=1 for more information

And with $MISE_VERBOSE:

> MISE_VERBOSE=1 mise install -f "pipx:*"
DEBUG ARGS: mise install -f pipx:*

Same thing with mise 2025.1.7 on FreeBSD 14.3

Also, when just running mise use pipx:... without specifying a version, mise uses the version of pipx instead of the version of the python package. E.g.

$ mise use pipx:flux-local

1.7.1 is the version of pipx, not flux-local; running mise use pipx:flux-local@7.5.6 works however.
