<#
    .SYNOPSIS
        Retrieves the localized string data based on the machine's culture.
        Falls back to en-US strings if the machine's culture is not supported.
    .PARAMETER ResourceName
        The name of the resource as it appears before '.strings.psd1' of the localized string file.
        For example:
            For WindowsOptionalFeature: MSFT_WindowsOptionalFeature
            For Service: MSFT_ServiceResource
            For Registry: MSFT_RegistryResource
            For Helper: SqlServerDscHelper
    .PARAMETER ScriptRoot
        Optional. The root path where to expect to find the culture folder. This is only needed
        for localization in helper modules. This should not normally be used for resources.
    .NOTES
        To be able to use localization in the helper function, this function must
        be first in the file, before Get-LocalizedData is used by itself to load
        localized data for this helper module (see directly after this function).
