Install poetry-shell-plugin

[gabeiglio]

With the release of poetry version 2.0.1 the shell command will only be available through installing the poetry-plugin-shell: see

This PR makes sure to install this plugin along with poetry

ah seems like poetry shell is moved to the plugin. I dont see poetry shell used anywhere in the repo. And i typically just use poetry run ...

@gabeiglio what is your use case for this?

[gabeiglio]

I usually follow this instruction from the docs to setup/activate the venv:

If you want to install the library on the host, you can simply run pip3 install -e .. If you wish to use a virtual environment, you can run poetry shell. Poetry will open up a virtual environment with all the dependencies set.

But, if other folks dont use this, then the docs could just point out that the shell needs to be installed separately

[kevinjqliu]

oh interesting. yea i think its good to update the docs to optionally install poetry shell. I've always just used poetry run ... maybe we can add that to the docs too

[gabeiglio]

Sounds good! Ill close this pr and open another one to update the docs
