Adds the latest docs code from cugraph repo

[acostadon]

Adds the latest docs code from cugraph repo also adds pyg to conda environment which is necessary to build docs.
Resolves #58

[BradReesWork]

A few items:

1. Now that all the docs are in one place, you might want to create subfolders under "_static" to organize files
2. The blogs and papers section is out of date

Looks good. Let's fix the CI failures in #46 first, and then once that's merged this should build successfully.

I just pushed some updates here in cda23fd

• added cugraph-pyg to dependencies.yaml
• added a CI job to check that files like conda environment files in the repo match dependencies.yaml
• updated pre-commit hooks to their latest versions by running pre-commit autoupdate
• remove the CUDA 11.8 and CUDA 12.2 conda env files checked into the repo, added a CUDA 12.5 one
  • the files in conda/environments/ are only meant for interactive development, they don't affect CI
  • CI is using the latest CUDA version RAPIDS supports, currently 12.5, so I think it's useful to have the local environment match
  • ref:

    cugraph-docs/.github/workflows/pr.yaml

    Line 38 in 2203a93

    container_image: "rapidsai/ci-conda:latest"

Will add some inline comments explaining these changes too.

This change, adding depends_on_cugraph_pyg to the all: dependency list, causes rapids-dependency-file-generator to automatically put the appropriate version of it into the file(s) in conda/environments/
