That's not what alt text is. It's for screen readers. A bunch of people
are way into ASCII art so alt text is needed. They are image
descriptions.

I recommend the following instead:
Just name the language on the line before the <pre> block.
ie.:

lua:
```
local function whatever() end
```

This way you aren't making an accessibility feature worse by trying to
overload it to be some generic metadata container.
