auro-accordion: disabled state

[tfales]

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

RAIN, an application supporting call centers, is interested in having support around a disabled state of the auro-accordion where a consumer can show initial information within the trigger but the collapse/expand functionality is disabled in the event that there is no additional data/context/information to display.

Describe the solution you'd like

Expand/collapse function is disabled, driven by an attribute, with an eye on accessibility and keyboard support. Other considerations include greying the text and potentially a cursor override on the whole trigger element.

Describe alternatives you've considered

For now, our implementation approach is to allow users to expand/collapse the accordion and within the content we'll show a placeholder message resembling something like "No data" or "Nothing to see here" but more appropriate verbiage given the full context.

Additional context

Here's an example screenshot of an initial design around baggage elements in RAIN. This shows an example of 3 separate accordions with active-expanded, active-collapsed, and inactive (disabled) state. The 3rd row/disabled state is what we're looking for support on. Please feel free to reach out to me with any questions.
