Escape code block to allow nested code blocks correctly per [this](https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks#fenced-code-blocks). Currently, copying the code and pasting into a github wiki doesn't render the code block as syntax highlighted code like the screenshot.
It looks like this:
<details><summary>CLICK ME</summary>
<p>
#### We can hide anything, even code!
```ruby
puts "Hello World"
```
</p>
</details>
Not this:
<details><summary>CLICK ME</summary>
<p>
#### We can hide anything, even code!
```ruby
puts "Hello World"
```
</p>
</details>
