[BUG] SiteTemplate not fetching Navigation Node Labels correctly

[Myjestic]

Reporting an Issue or Missing Feature

I created a xml template with Get-PnPSiteTemplate or C# from a Site that uses a foldable node in Navigation. This node is set as "label" without a link.

The Label will be exported as:
<pnp:NavigationNode Title="Administration" Url="" IsExternal="true">

If applying the template the node will be created but it is linked to the homepage of the SP-Site. It should not be clickable.

Expected behavior

Nodes marked as label should be exported and imported as label, not as clickable link.

Actual behavior

Thats what a formerly label will be after provisioning:

Steps to reproduce behavior

• create label in Navigation (modern page)
• export navigation via Get-PnPSiteTemplate to xml template file
• import in new site with Invoke-PnPSiteTemplate using the xml template file
