This PR refactors the translation mechanisms to be a bit more straightforward to manage in the future. I've used the guidance from the Internal State chapter of the R package book to inform the solution:
translation strings all live in R/utils-translate.R and are not duplicated
the source for the translation strings are stored in these$translations$src.
all translations are intialised by establish_translation_vars() when sandpaper is loaded
strings are translated to lesson language by set_language() when lesson is loaded
documentation has been updated.
I've also updated the documentation to automatically include a list of all translatable strings.
Note that this could serve as scaffolding for refactoring the other global variables to not be so painful to implement.
