wordle example doesnt properly compile in playground

[stchang]

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
