Micromamba ignores pip dependencies from new lockfiles

[maresb]

The new lockfile format allows for the installation of PyPI packages corresponding to the - pip [...] section of environment.yml. However, it seems that this is not yet supported by micromamba.

To reproduce, create environment.yml:

name: test-pip-deps
channels:
- conda-forge
dependencies:
- pip
- pip:
  - cowsay
platforms:
- linux-64

and generate a new-style lockfile conda-lock.yml by running

conda-lock

Create an environment via conda-lock, and it works:

conda-lock install --name conda-lock-pip-deps conda-lock.yml
micromamba activate conda-lock-pip-deps
cowsay moo
micromamba deactivate

Try with micromamba, and it doesn't work:

micromamba create --yes --name micromamba-pip-deps --file conda-lock.yml
micromamba activate micromamba-pip-deps
cowsay moo
micromamba deactivate
