Migrate readthedocs with github pages

[mdenolle]

Merge documentations under the same framework

Here's an example of integrating ipynb notebooks and .md files: https://github.com/OSOceanAcoustics/echopype/tree/main/docs/source

First goal is to add the tutorials/cloud and tutorials/cli to the jupyter book by adding them to tutorials/_toc.yml. You can test this locally by running

cd tutorials
pip install -r requirements.txt
jb build . -W

This is what the .github/workflows/notebook.yml workflow does during PRs and releases.

We also need update the docs badge link in the README to point to the github pages

@IshikaKhandelwal - can you:

• Rename the docs folder to doc_old
• Update all links in the README (and any others you find) from readthedocs.org to https://noisepy.github.io/NoisePy/
  • For the docs badge, you can point to the notebooks workflow: https://github.com/noisepy/NoisePy/actions/workflows/notebooks.yml/badge.svg
• Make noisepy_scedc_tutorial the root: in the _toc.yml
• Add noise_configuration as a file

@mdenolle Once this is done, we probably want to take down the readthedocs page: https://noisepy.readthedocs.io/en/latest/index.html? Anything from there we want to preserve?

we can keep the old files into a doc_old folder
