[FEATURE] Ability to set serverless image client version for notebook tasks

[Korijn]

Use-cases

My goal is to deploy jobs with notebook tasks on serverless compute, using the serverless image client version 2.

Attempted Solutions

I tried to create an environment and add environment_key to the task, but it gives an error telling me to use %pip install inside the notebook. Of course that's not going to allow me to configure the serverless image client version 2.

To be clear, I don't need to install any dependencies. I just want to use the new serverless image client version because it has more recent Python version.

Proposal

I don't really know why it isn't supported so I can't really make a proposal.
