Kamran Ahmed ee4b7305a2 Adds ByteByteGo guides and links (#106)
This PR adds all the guides from [Visual
Guides](https://bytebytego.com/guides/) section on bytebytego to the
repository with proper links.

- [x] Markdown files for guides and categories are placed inside
`data/guides` and `data/categories`
- [x] Guide links in readme are auto-generated using
`scripts/readme.ts`. Everytime you run the script `npm run
update-readme`, it reads the categories and guides from the above
mentioned folders, generate production links for guides and categories
and populate the table of content in the readme. This ensures that any
future guides and categories will automatically get added to the readme.
- [x] Sorting inside the readme matches the actual category and guides
sorting on production

Containerization

1. Use official images

This ensures security, reliability, and regular updates.

2. Use a specific image version

The default latest tag is unpredictable and causes unexpected behavior.

3. Multi-Stage builds

Reduces final image size by excluding build tools and dependencies.

4. Use .dockerignore

Excludes unnecessary files, speeds up builds, and reduces image size.

5. Use the least privileged user

Enhances security by limiting container privileges.

6. Use environment variables

Increases flexibility and portability across different environments.

7. Order matters for caching

Order your steps from least to most frequently changing to optimize caching.

8. Label your images

It improves organization and helps with image management.

9. Scan images

Find security vulnerabilities before they become bigger problems.
