Poetry version solving fails when running `jf poetry install`

Describe the bug

When running poetry commands, the JFrog CLI will invoke poetry update, which now fails following the update to version 2.87.0.

Current behavior

When running any jf poetry command (for example jf poetry install):

Reproduction steps

1. Create a project: poetry init
2. Add a dependency: poetry add boto3
3. Run jf poetry-config
4. Run jf poetry install

Poetry version: 2.1.3

Expected behavior

The issue seems related to the removal of the /simple within the source URL in https://github.com/jfrog/jfrog-cli/pull/3247. When adding back /simple, poetry update now works.

JFrog CLI version

2.87.0

Operating system type and version

MacOS 26.2

JFrog Artifactory version

SaaS

JFrog Xray version

Start by reviewing the source-URL change in pull request #3247 and reproduce the issue with poetry init, poetry add boto3, jf poetry-config, and jf poetry install. Done means the JFrog CLI-generated Poetry source URL lets poetry update resolve the dependency successfully.
