Use modern material theme for docs

[lc0rp]

Background

We're using a ReadTheDocs theme that hasn't changed in years, and isn't the default, more modern MkDocs theme.

@RaghavKumar suggested the Material UI theme, and after using it, the docs feel way more accessible.

It's also the most popular MkDocs theme, by far, according to https://github.com/mkdocs/mkdocs/wiki/MkDocs-Themes.

Changes

• Updated requirements.txt to include the mkdocs-material package
• Changed theme in mkdocs.yaml
• Configured some theme options like color schemes, navigation, etcetera
• Added logo to docs/imgs (for favicon)

Documentation

N/A - these are the docs

Test Plan

Played around with it in-browser for the past 3h :-(

I think this is a great idea. I love material. Some things from my own technical documentation projects.

In the theme you can add:

theme:
    name: material
    features:
      - content.code.copy

and that will enable the little click to copy box in code snippets for people looking at our docs.

I also just blanket put in

markdown_extensions:
  - abbr
  - admonition
  - attr_list
  - def_list
  - footnotes
  - md_in_html
  - pymdownx.arithmatex:
      generic: true
  - pymdownx.critic
  - pymdownx.caret
  - pymdownx.details
  - pymdownx.emoji:
      emoji_index: !!python/name:materialx.emoji.twemoji
      emoji_generator: !!python/name:materialx.emoji.to_svg
  - pymdownx.highlight:
      anchor_linenums: true
      line_spans: __span
      pygments_lang_class: true
  - pymdownx.inlinehilite
  - pymdownx.keys
  - pymdownx.mark
  - pymdownx.snippets:
      auto_append:
        - includes/abbreviations.md
  - pymdownx.superfences:
      custom_fences:
        - name: mermaid
          class: mermaid
          format: !!python/name:pymdownx.superfences.fence_code_format
  - pymdownx.tabbed:
      alternate_style: true
  - pymdownx.tasklist:
      custom_checkbox: true
  - pymdownx.tilde
  - tables
plugins:
  - table-reader
  - search
extra_javascript:
  - https://unpkg.com/tablesort@5.3.0/dist/tablesort.min.js
  - _javascript/tablesort.js
  - _javascript/mathjax.js
  - https://polyfill.io/v3/polyfill.min.js?features=es6
  - https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js

and add

window.MathJax = {
  tex: {
    inlineMath: [["\\(", "\\)"]],
    displayMath: [["\\[", "\\]"]],
    processEscapes: true,
    processEnvironments: true
  },
  options: {
    ignoreHtmlClass: ".*|",
    processHtmlClass: "arithmatex"
  }
};

document$.subscribe(() => {
  MathJax.typesetPromise()
})

to docs/_javascript/mathjax.js

and

document$.subscribe(function() {
  var tables = document.querySelectorAll("article table:not([class])")
  tables.forEach(function(table) {
    new Tablesort(table)
  })
})

to docs/_javascript/tablesort.js.

This set of stuff enables all the features in material (which are turned off by default).

Happy to let you decide what you want to include here, but would like to hear your thoughts.

[lc0rp]

These are great! Testing them now...

It seems to be missing the extension that does highlighting for indented code blocks

@lc0rp @collijk I made a small correction to a sample YAML snippet that came from this PR. Would appreciate a review, thank you.
The PR is #5168 .
