[mamba] RuntimeError: Could not set URL

It seems that the problem comes from not setting the url here.
I'm not sure where the url to use should be coming from (conda, channel url, ...)?
@AntoinePrv any ideas?

@Hind-M did you manage to reproduce the issue.
Perhaps we should switch to

    prefix_data = api.PrefixData(context.target_prefix)
    prefix_data.add_packages(api.get_virtual_packages())
    repo = api.Repo(pool, prefix_data)
    repos.append(repo)

As done in #2632 where we remove uses of load_conda_installed.

Yes, by running mamba env update -p path_to_test_env --file test_env.yml

test_env.yml:

channels:
  - conda-forge
dependencies:
  - python=3.11.4

and having a python version < 3.11.4 (3.10.12 in my case)

Perhaps we should switch to

    prefix_data = api.PrefixData(context.target_prefix)
    prefix_data.add_packages(api.get_virtual_packages())
    repo = api.Repo(pool, prefix_data)
    repos.append(repo)

Yes awesome, thanks!
