Implement Enhancing Flexibility with Customizable Default Folder Path

[mdaneri]

Implementation Details for #1243

Configuration via server.psd1:
Users can define custom paths for the default folders within the server.psd1 configuration file. This approach maintains Pode's configuration-driven design and ensures ease of setup. For example:

@{
    Server = @{
        DefaultFolders = @{
            Public = 'c:\custom\public'
            Views  = 'd:\shared\views'
            Errors = 'e:\logs\errors'
        }
    }
}

New PowerShell Functions:
To support this feature dynamically, we propose adding two new functions:

Set-PodeDefaultFolder: Allows users to programmatically set the path for a default folder during runtime.

Parameters:
-Type: Specifies the folder type (Views, Public, or Errors).
-Path : Defines the new file system path for the folder.

Get-PodeDefaultFolder: Enables querying the current path settings for the default folders.
