Unable to set up pulp-python sync from JFrog local pypi repository

Start by reproducing the authenticated sync described in the issue with a JFrog local PyPI repository, using the listed pulp-python 3.11.0 setup and remote credentials. Compare the request URL and authentication seen in the JFrog logs with the configured remote; done means the sync succeeds with credentials passed correctly and the package path is formed as expected.

Describe the bug
I set up a Pulp python remote pointing at a local JFrog pypi repository ("url": "https://<redacted>/artifactory/api/pypi/pypi-local/simple"), providing valid credentials in the process (with username and password), and linked it with a Pulp python repository and distribution. However, it appears that the credentials are not being passed during the requests when syncing, or the URL is being malformed, or something. From JFrog logs (note the non_authenticated_user and 401):

2024-05-14T16:33:15.472Z|<redacted>|<redacted>|non_authenticated_user|GET|/api/pypi/pypi-local/simple/pypi/<redacted>/json|401|-1|0|1|bandersnatch/6.1.0 (cpython 3.9.18-final0, Linux x86_64) (aiohttp 3.9.3)

For what it's worth, that URL also looks strange... I would expect .../simple/<redacted>/json, not .../simple/pypi/<redacted>/json. It's worth noting that Artifactory requires the username/password to be included in the URL but Pulp prevents that:

Error: {"url":["The remote url contains username or password. Please use remote username or password instead."]}

To Reproduce
Steps to reproduce the behavior:

1. Create a local pypi repository in JFrog.
2. Create a Pulp remote pointing at the JFrog pypi repository (and then set up a Pulp repository and distribution as needed to sync it).
3. Attempt an authenticated sync.

Expected behavior
The sync should happen successfully.
