Conda does not respect --override-channels option when using libmamba solver

What happened?

After encountering the issue seen in #489, I tried to use the --override-channels option to explicitly specify only the conda-forge channel. However, conda still attempted to use the same channels as in that issue, despite the --override-channels option. The same behavior is NOT seen when I turn off the libmamba solver.

I think this was fixed in 23.9.0 via #274. Your conda info reports 23.7.0, so I'd try upgrading first to see if the issue you brought up is already addressed in the latest releases.
