Fix some mistakes in the pt_BR translation

[Space-G]

Changes:

Solves #1064

List of changes:

Original Name	Current translation	Suggested translation	Reasoning
Gantry and Dolly	Pórtico e Dolly	Grua e Vagão	Aesthetics, and personally less confusing but this one is abstract
V Stitch	Ponto V	Costura V	Keeps the meaning, reduces ambiguity. Avoids confusion with "G Spot" (Evita assimilação a "Ponto G" mantendo o significado)
The Tomb of Mad Carew	A tumba de Mad carew	A tumba de Mad Carew	Capitalization (Capitalização)
Shockwave Rider	Cavaleiro Shockwave	Shockwave Rider	Keeps the reference to the book that wasn't released in portuguese (Mantém a referência ao livro de título Shockwave Rider)
On the [VW]aterfront	À [bv]eira-mar	Sindicato de [LV]adrões	Keeps the reference to the movie, using it's released title here (Mantém a referência ao filme On the Waterfront)
The Voon Show	O show de voons	The Voon Show	Keeps the reference to the british radio show (Mantém referência ao show humorístico de rádio The Voon Show)
The 9 O'Clock News	Notícias das 9 horas	Jornal das 9	"Jornal" instead of "notícias" because that's how we call the program that shows the news on TVs and Radios. It's also what "newspaper" is called. The omission of the word "horas" (hours) is due to how we refer to programs in radios and television. (O jornal é autoexplicativo, a omissão da palavra "horas" reflete o jeito comum de falar sobre programas de televisão.)
Panic Room	Sala de Pânico	O quarto do pânico	Keeps the reference to the 2002 movie, using it's released pt-br name (Mantém a referência ao filme Panic Room, cujo nome em pt-br é O quarto do pânico)
Cosmic Creepers	Trepadeiras cósmicas	Crepúsculo Cósmico	Is the name of the cat in the brazillian dubbed version of Bedknobs and Broomsticks, keeping the original reference. (É o gato da bruxa aprendiz Eglantine Price, no filme Se a minha Cama Voasse, dublado em pt-br.)
The Sensible Room	A sala sensível	A sala sensata	It's a false cognate*
Brass sent us under the top	Bronze nos enviou abaixo do topo	O alto comando nos enviou	Translates "Brass" as the metal, instead of the military slang*
Vertigo	Vertigem	Um Corpo que Cai	Vertigo translates correctly, but the movie had a different title in PT-BR*

Would you like to be added to the credits for pt_BR translation?

Yes, please, that would be an honour, thank you so much!

3 translations were actually suggested by zaratruza on Cohost, they might want to be credited aswell, maybe.

Sorry, we'll put for this sort of contribution in the github contributors section! The main translation credits are for the localisation teams themselves. (We hadn't discussed this internally, so apologies for the confusion)
