PT-BR tray menu translation fix

[tulio150]

The option to show/hide the main window sis translated incorrectly for brazilian portuguese
Hide = Esconder is corrent
Show = Scomo is not even a word

The corect should be

Show = Mostrar, which is opposite for Esconder

This is caused because of the ampersand and automatic translator "S&how" got translated as "S&como" because "how"was translated to "como"

Thanks for helping with translations! However, changes to translations as well as new translations are submitted to Bitcoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works. So we do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
