feat: Add static file import system for docs (#3882)

# What does this PR do?

Add static file import system for docs

- Use `remark-code-import` plugin to embed code at build time
- Support importing Python code with syntax highlighting using
`raw-loader` + `ReactMarkdown`

One caveat is that currently when embedding markdown with code used the
syntax highlighting isn't behaving but I'll investigate that in a follow
up.

## Test Plan

Python Example:
<img width="1372" height="995" alt="Screenshot 2025-10-23 at 9 22 18 PM"
src="https://github.com/user-attachments/assets/656d2c78-4d9b-45a4-bd5e-3f8490352b85"
/>

Markdown example:
<img width="1496" height="1070" alt="Screenshot 2025-10-23 at 9 22
38 PM"
src="https://github.com/user-attachments/assets/6c0a07ec-ff7c-45aa-b05f-8c46acd4445c"
/>
