Allow pipx to use sytem certificates

Describe the bug pipx install fails due to corporate network/proxy with self-signed certificate.

From the log:

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:997)'))': /simple/hatch/

ERROR: Could not find a version that satisfies the requirement hatch (from versions: none)

Note that if I create a venv, things work as expected. So the system python/pip handles the (installed) self-signed cert:

syncer on  chore/setup-hatch [!?] 
❯ python3 -m venv .venv

I'm using the zipapp (pipx.pyz), version (1.2.0)

My environment is Ubuntu 22.04 running in WSL on Windows 10.

Python is 3.10.6

How to reproduce

syncer on  chore/setup-hatch [!?] 
❯ python3 /home/jim/dev/afa/syncer/.deps/pipx/1.2.0/pipx.pyz --verbose install hatch
usage: pipx.pyz [-h] [--version] {install,uninject,inject,upgrade,upgrade-all,uninstall,uninstall-all,reinstall,reinstall-all,list,run,runpip,ensurepath,environment,completions} ...
pipx.pyz: error: unrecognized arguments: --verbose

To reproduce I guess you have to be in an environment that has a proxy with a self-signed cert.

Expected behavior pipx successfully installs package.
