make expandable hover content accessible to screen reader users

[meganrogge]

We will want to indicate that the expand / contract context actions in a hover exist to screen reader users.

When these are present, we should add an AccessibililtyVerbositySetting and hint to the hover's aria label that tells a user to open a help dialog, where we can indicate these actions, what they do, and the keybindings.

We will also probably want to support these actions in the accessible view, similar to what we do with next and previous in the chat response accessible view so users don't have to navigate bw the widget and the accessible view.

@aiday-mar I'm not sure what the current status of this is. Should we work on this in May?

Hi @meganrogge thank you for pinging on this issue. The PR on making the hover expandable is not merged yet, we are planning on merging it beginning of next iteration. Here is the link #204721. Perhaps after this is done, we can look into making the hover more accessible?
