Portuguese (Brazilian) translation of entity.stray is incorrect

Summary:

**In the pt_BR.lang file, on line 1718, the key entity.stray is translated to "Invocar nômade" but it should just be "Nômade." "Invocar nômade" is the translation for the Stray Spawn Egg and literally translates to "Invoke Nomad."

Impact:

Incorrect and inconsistent translation.

 

Expected Results:

**All other translation keys in this section are just the name of the entity such as entity.skeleton.name=Esqueleto
