fix(i18n): correct settings name translation in pt-BR (#11172)

# Pull Request Template

## Description

In pt_BR language, some strings are being mispelled, the correct word
would be "Configurações" but instead it is being showed as
"Confirgurações", which is wrong.
Fixes: https://github.com/chatwoot/chatwoot/issues/11149

## Type of change

- [x] Bug fix (non-breaking change which fixes an issue)


## How Has This Been Tested?

I've compiled the new translations and I compared the problematic
strings in PT_BR to check if it was still with the "Confirgurações" word
instead of "Configurações"
