Website feature request: Enable line wraps on code blocks

[nikolasburk]

Sometimes it's useful to be able to "wrap lines" automatically on code blocks to avoid a horizontal scroll. It would be great if this could enabled on a per-code block basis, e.g.:

```line-wrap=true
? The migration `20210310143435_change_type` was modified after it was applied.
 We need to reset the PostgreSQL database "migrate-example" at "localhost:5432".
 Do you want to continue? All data will be lost. » (y/N)
