Improve installation about kglab

[Mec-iS]

we would like to provide different alternatives for installation, one of which can be poetry. ideally the requirements definition should be same between requirements.txt and pyproject.toml

I will update the readme with install instructions for poetry and pipenv to install as a pypi package to use in a project.
I will also make updates to install the dev/test tutorial requirements with poetry and pipenv.
I'll create a pyproject.toml for poetry and a Pipfile for pipenv.

Created #275 to split changes

Outstanding, using poetry would be a nice improvement for kglab !

We have support for conda (especially for the RAPIDS integration, e.g., cuGraph, etc.) and there's a brief mention in the README for that.

@ceteri @Mec-iS are you wanting to move the KGLab package build to poetry?

Something less 2008-ish :)

It gets interesting to support a wider range of alternatives for installation, given that the RAPIDS parts can only be installed with conda which is specifically configured through the NVIDIA release selector https://rapids.ai/start.html#get-rapids

That said, we don't want to become a conda-only package.

I'll do a bit of poking around and come back with some ideas for pipenv and poetry
