Cannot move focus to facet category headers to open/close

[dbranchini]

Add the ability to move focus to facet category headers and allow users to open/close each facet category using the keyboard.

Consider doing in geoblacklight, not in earthworks

Works in searchworks, so may be ok in blacklight. Look at potential overrides in geoblacklight causing an issue.

tabindex should be set to a reasonable value

could try tabindex="0", which makes the element focusable in sequential keyboard navigation after any positive tabindex values

Investigating now. This seems to be occurring in the main branch of blacklight right now

Turns out focus is being set, it's just not visible since there is no border color when we are focused. See https://stanfordlib.slack.com/archives/C0AAK1HNY/p1724799431275469

There may be two actions needed:

1. Set a specific color for Earthworks in the CSS
2. Set a default color in Blacklight so other apps will at least inherit something (instead of blank)

I think Niqui is working on a fix in component library.

Needed another update...will be fixed by sul-dlss/component-library#37 when it's merged, a new release and cut, and Earthworks is updated to use the new release.

Here is how it will look (tested in localhost manually):

Seems to be working now. Thank you!
