Add langauge files

[circlecube]

Proposed changes

This adds a po file for each language:

• Spanish
• Portuguese (bonus)
• German
• Dutch
• French
• Italian
• English (Australia) - which is a copy of the default English
• English (UK) - another copy of English but updates "trash" to "bin".

These translations were created via crowdin AI assisted translations.
Runs composer run i18n command to:

• gather all translation strings in pot file
• update all po files with strings and source lines
• generate all mo files from latest po files
• generate all json files from latest po files

This gets us to a starting point for translations. Quick testing shows there are still strings that need to be using i18n functions. It looks like I've got all strings that are using the i18n functions translated by looking at the po files though, so as we make more available we'll need to continually add the translation functions, the pot file should pick it up and copy them into the po files - we'll need to make sure to add the translation though.

There are also sections of the plugin that come from modules that do not have translations for all languages or need to be updated to be i18n/l10n compatible.
