wordle example doesnt properly compile in playground

It doesn't like the `(require "wordle-words.rkt")`. Seems to be due to using `--stdin` flag in combination with an absolute path `require`

Error message is: `resolve-module-path-index: can't resolve "self" with non-path relative-to: #f`

A workaround at the moment is to install the library as a collection on the server
