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

+
+Scalability, Availability, Reliability, and Performance. They are the most critical components to crafting successful software systems.
+
+Let’s look at each of them with implementation techniques:
+
+*   **Scalability**
+
+    Scalability ensures that your application can handle more load without compromising performance.
+
+*   **Availability**
+
+    Availability makes sure that your application is always ready to serve the users and downtime is minimal.
+
+*   **Reliability**
+
+    Reliability is about building software that consistently delivers correct results.
+
+*   **Performance**
+
+    Performance is the ability of a system to carry out its tasks at an expected rate under peak load using available resources.
