auro-sidenav: ability to nest sidenavsection

[marnel-mangrubang]

Is your feature request related to a problem? Please describe.

The NDC pages are using the auro-sidenav component as the main navigation between pages. There is a need to nest the entire sidenav into a sidenavsection in order to support more sections inside of the sidenav. https://www.alaskaair.com/content/ndc/air-shopping/air-shopping-rq

Page with the attempted nesting of sidenavsections inside of a generic text component:

The problem we are seeing when trying to nest a sidenavsection is that the expandable section only expands to a fixed height, which cuts off the rest of the menu items.

Describe the solution you'd like

We would like to be able to nest sidenavsections so that we can achieve a 2-tier collapsable menu.

Describe alternatives you've considered

Alternative solution would be to add labeling above each section instead of having them collapse, however this leads to cluttered experience for the guest.

Additional context

In the near future, we plan to add more navigation menu items and would like to be able to collapse them instead of showing all the options to the guest.
