H5P Editor fails to use chosen language

Problem/Motivation

The H5P editor fails to use your chosen language and defaults to English.

Steps to reproduce

• Enable Locale module
• Navigate to /admin/config/regional/language and add French as another language
• Navigate to /admin/structure/block and add the Language Switcher block to the header or footer
• Use the language switcher to set your language to French
• Add / edit an H5P item
• The H5P Editor labels and descriptions are in English, even though you set your language preference to French.

Proposed resolution

The changes in 📌 Remove vendor directory and composer.lock from project repository Active resulted in the $chosenLanguage value in getTranslationFilePath() being root relative instead of relative. As a result, the file_exists() check doesn't find the file. A simple fix is to prepend the root relative path with the DRUPAL_ROOT value so file_exists() can find the file.

Remaining tasks

The fix above.
