Poetry 2.x causes the package manager to show an empty list in the sidebar

[robd518]

Describe the bug

Referenced https://github.com/marimo-team/marimo/issues/2923

In poetry 2.x+, the --no-dev flag no longer exists. It looks like they prefer that we use --without, --with, and --only

As a result, the Package Manager tab in the sidebar doesn't display the currently installed packages.

https://github.com/marimo-team/marimo/blob/e02859e1c6d2eca1c0af5ceca09f9b45a50e4211/marimo/_runtime/packages/pypi_package_manager.py#L583
