Provide a quicker way to update conda env after python is installed in it

[karrtikr]

Once Jupyter installs ipykernel into the env, python is installed along with it. To update the env, right now running the refresh api and waiting for the env change event to get fired takes around 60s according to #20634 (comment). Potential solutions:

• See if it's possible to use resolveEnvironment to quickly resolve the latest details for such envs. (either the same API or a new parameter on the same API)
• Provide a private API to forcibly just refresh conda envs, so we need not do a full refresh.
• Add a watcher for conda envs without python.
• Investigate why the refresh for envs takes 60s and possibly prioritize refresh of conda envs over others.

This is my quick hack which was very very effective
In the resolve api

• check of this cpnda env without python
• Then check if python file now exists (the executable is predictable, currently it’s the id)
• If all true, then get the new python env details
