Option to indent code in a #region

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.

Summary

When writing code, I depend heavily on regions to keep things clean. Sometimes even nested regions. I would love it if we have the option to indent the code in a region to easily find where a region starts and ends.

#region: Hello World!
Write-Host 'Hello World!
#endregion

Should be (optinally)

#region: Hello World!
    Write-Host 'Hello World!
#endregion

Would be even cooler if the indent is adjustable to 1 or 2 spaces instead of 4

Proposed Design

Add option in the formatter to indent regions and specifying by how many spaces.

Comece pelo ponto de entrada do formatter descrito na issue e determine como os limites das regiões e a indentação são tratados atualmente. Defina a quantidade de indentação configurável e verifique se a formatação indenta opcionalmente o código dentro de regiões aninhadas, preservando o comportamento existente quando a opção estiver desabilitada.
