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.

Beginne am im Issue beschriebenen Einstiegspunkt des Formatierers und ermittle, wie Regionsgrenzen und Einrückung derzeit behandelt werden. Definiere die konfigurierbare Einrückungsgröße und überprüfe, dass die Formatierung Code innerhalb verschachtelter Regionen optional einrückt und das bestehende Verhalten beibehält, wenn die Option deaktiviert ist.
