"Leggings" item group name is not translated in Brazillian Portuguese

There is a group of items in the creative inventory for every type of armor, like leggings, boots, helmets, etc. The item group name is translated for every language used. However, in Brazillian Portuguese, this doesn't seems to happen with the leggings group name, making such text not translated for Portuguese.

Steps to replicate

1. Set the game language to Brazillian Portuguese, and go to the creative inventory.
2. Go to the equipment tab. Notice how the boots, helmets, and chestplates' item group names are translated.
3. Look at the leggings group name

Observed

The item group for leggings is not translated.

Expected

The item group name for leggings should be translated, potentionally to "Calças".
