Code Formatting: Whitespacing ValidateSet

Summary of the new feature

I've this validateset:

Sometimes I want it to have 2-3 per line so I start removing pressing delete button and I end up with what you see above. It would be nice if I could then press format and it would remove that unnessecary whitespace. While initially I thought it could be all automatic you said on twiter that it may quickly get out of control. I agree of course (even thou I would ant different styles to be available - like 3 validateset params per line) but at least maybe this can be addressed? It's just making sure there is only 1 white space per line (or defined value if it's needed).

Comece localizando o formatter ou comando de formatação no PSScriptAnalyzer e revisando as regras ou os testes existentes relacionados a espaços em branco. Esclareça se o objetivo é um único estilo de espaços em branco ou uma quantidade configurável de itens por linha e, em seguida, defina testes que cubram o exemplo de ValidateSet e a saída formatada esperada.
