Normalize and fixes missing locales

[PedroAugustoRamalhoDuarte]

Description

The goal in this issue is normalize and fixes some missing locales, for this i have done the following tasks:

• Install i18n-tasks gem and configure for avo
• Normalize locale files
• Fixes inconsistent interpolations for tr locale
• Adds missing keys for pt-BR (my main language) and ro (I used google translate for that)
• Adds specs for no more missing keys

In this PR i do not fixes any opened issues, but we talk a little bit for this change is this PR #1216
OBS: I have not checked for unused translations, because there are a lot, i thinks this should be done in another PR.

Checklist:

• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas

Manual review steps

1. I run i-18n-tasks and correct one by one.
2. Print for missing keys for pt-BR and ro locale

@adrianthedev i run the normalize locale again to fixes the specs, and we need to add this ignore missing i think because this bug: glebm/i18n-tasks#473:

ignore_missing:
  - 'avo.field_translations.file'
  - 'avo.field_translations.people'
  - 'avo.number_of_items'
  - 'avo.resource_translations.user'
  - 'avo.x_items_more'

Ok. got it. It seemed weird having that one ignored.
Thanks for letting me know. It's ok to merge after all tasks finish.
