Bring back deprecated rules

Historically PSScriptAnalyzer has had a number of rules that have been deprecated & then removed from the available set of rules, one such example is AvoidUninitializedVariables

I propose that we bring them back, but publish them contained in a separate module so that others could still use them if they choose to do so.

This realistically shouldn't equate for much additional engineering work & would provide a better mechanism for rule development & deprecation in future whilst not loosing potentially useful rules in specific cases.

A proposta é restaurar as regras obsoletas do PSScriptAnalyzer, incluindo AvoidUninitializedVariables, em um módulo separado. Comece localizando as implementações de regras existentes ou removidas e a estrutura do módulo; considera-se concluído quando as regras obsoletas forem publicadas separadamente e continuarem utilizáveis sem alterar o conjunto de regras padrão disponível.
