devel/rubygem-i18n-tasks-rails61: New port

i18n-tasks helps you find and manage missing and unused translations.

This gem analyses code statically for key usages, such as
I18n.t('some.key'), in order to:

• Report keys that are missing or unused.
• Pre-fill missing keys, optionally from Google Translate or DeepL Pro.
• Remove unused keys.

Thus addressing the two main problems of i18n gem design:

• Missing keys only blow up at runtime.
• Keys no longer in use may accumulate and introduce overhead, without you knowing it.
