nav_list empty links

This is an enhancement or feature.

Summary

An empty-string child url in nav_list should produce an unlinked title.

Context

By default, a nav_list child entry without a link defaults to a link to the current page.

There are times when what you really want is NO link. See the sidebar here for an example. To maintain backwards compatibility, this change enables this behavior only when the url property is explicitly set to an empty string, like this:

entity-manager:
  - title: Packages
    children:
      - title: <strong><code>entity-manager</code></strong>
        url: '' # 👈 THIS!
      - title: <i class="fa-brands fa-github fa-lg"></i>&nbsp;&nbsp;GitHub
        url: https://github.com/karmaniverous/entity-manager
      - title: <i class="fa-solid fa-heart fa-lg"></i>&nbsp;&nbsp;NPM
        url: https://www.npmjs.com/package/@karmaniverous/entity-manager
      - title: <i class="fa-solid fa-book fa-lg"></i>&nbsp;&nbsp;API
        url: https://docs.karmanivero.us/entity-manager/
      - title: <i class="fa-solid fa-comment fa-lg"></i>&nbsp;&nbsp;Help

[iBug]

What about replacing "empty URL" with either null or false, so that {% if child.url == "" %} can be written as {% if child.url %}? I also think these are more explicit than an empty string.

I was concerned about backwards compatibility. I think if you make that change a bunch of people my find their existing links no longer working as expected.
