Docusaurus 3 Upgrade

I've upgraded Docusaurus to v3 and there're some breaking changes affecting us:

See Docusaurus breaking, MDX 2 breaking and MDX 3 breaking for more info

• Prefer .mdx format over .md. .md still works, but .mdx has more integrations, features and slightly different validation.
• If you're using VSCode, please install MDX and ESLint plugins for linting.
  Probably, we can setup another linter later.
• MDX Playground is your new friend
• Validate mdx files with this tool:

npx docusaurus-mdx-checker

• require modules is not supported any more, use ESModules instead

Coding

• Auto links doesn't work any more, use standard MD links instead

<http://openbb.co> ❌ Error
[http://openbb.co](http://openbb.co) ✅ Valid

• Don't open multiple tags on one line:

❌ Error
<details><summary>How do I select commands instead of typing?</summary>
. . . More details
</details>

✅ Valid
<details>
  <summary mdxType="summary">How do I select commands instead of typing?</summary>

  . . . More details (1 empty line above is mandatory)
</details>

• Screen the braces with backslash or wrap into code block

{stars,forks}    ❌ Error
\{stars,forks\}  ✅ Valid
`{stars,forks}`  ✅ Valid
{ 1 + 2 }        ✅ Valid, returns 3

• Always wrap math equations into $ _ $ or $$$ for multiline block

$D_{i,j} = \sqrt{(1-\rho^{distance}_{i,j})}$

• If you're using katex in tables, there're 2 options:

a. Make sure your formula is not using |. Screening it with backslash works, but cause glitches

| Column A        | Column B                                         |
| --------------- | ------------------------------------------------ |
| Math formula is | $D*{i,j} = \sqrt{(1-\|\rho^{pearson}\_{i,j}\|)}$ |

b. Use HTML tables

<table>
  <tr>
    <td>Column A</td>
    <td>Column B</td>
  </tr>
  <tr>
    <td>Math formula is</td>
    <td>$D*{i,j} = \sqrt{(1-|\rho^{pearson}\_{i,j}|)}$</td>
  </tr>
</table>
