Create conda store environment

[peytondmurray]

Summary

This PR adds support for creating conda-store environments.

Changes

• Added ability to create conda-store environments.
• Move the parseEnvironment function out of the CondaStorePackageManager - it's used by the CondaStoreEnvironmentManager as well, and doesn't need to be part of the class.
• Fixed issue where not all packages were being shown if there was either no installed or no available packages.
• Added async to the rest of the empty CondaStoreEnvironmentManager functions which should have had that keyword from before.
• Made the output of tsc use the pretty format - it's much easier to spot compilation errors in the terminal with this setting

Here's a demo of me creating an environment. I'll try to get someone else to test this and comment here as well:

Also, @fcollonval (or anyone else) if you would like to meet to get a conda-store server up and running, we can do that too. I'll also look into setting up a remote conda-store server so that you don't have to worry about getting it running locally.

@fcollonval In case you (or anyone else) have time and are interested, you can get the conda-store server up and running in a few steps:

1. git clone git@github.com:quansight/conda-store
2. Add the following line to conda-store/examples/docker/assets/conda_store_config.py to allow all users to create environments:

c.RBACAuthorizationBackend.unauthenticated_role_bindings = {
    "*/*": {"admin"}
}

3. Run the conda-store server:

   cd conda-store/examples/docker
   docker compose up --build

The server should now be running at http://localhost:5000. Navigate to JupyterLab and open the Conda Store Packages Manager, and you should be able to create an environment. Because it takes a little while for the environment to build, you may have to refresh the packages to see anything.

Thanks @peytondmurray for the information.
