Feature: Add q-search-results-list web component.

[fchasen]

Description

Implements a new q-search-results-list web component to display and manage the searching a Pagefind index, replacing the current search results template and display logic.

• The component takes a query attribute to search for in a Pagefind index.
• Removes the updateSearchResults and displaySearchResults methods, as lit will handle batching UI updates.
• Enables adding figures to the Pagefind index.
• Adds subresults, contributors metadata and figures with image previews to the search results.
• Adds excerpts with search query highlighting to all search result items.
• Removes type and word count metadata from the search results.

Additional Comments

Thumbnail handling for figures will be added once they are a size that can be used.

Ahead of the code review, this is looking really good @fchasen. It's exciting to see it in action. The two small style changes I'd make are:

.search-subresults {
  margin-left: 3rem;
}
.result-excerpt mark {
  background-color: var(--highlight-color, #F9F9A3);
}

Following the pattern of how you handled the other color items, the highlight it based on an as-yet non-existent css variable, but falls back to the highlight color value currently defined in content/_assets/styles/colors.scss.

I also played around with doing something to indicate that the excerpts are excerpts, but ultimately it felt too busy for me and probably unnecessary.

.result-excerpt:before {
  content: '... ';
}
.result-excerpt:after {
  content: ' ...';
}

Finally, on a non-style note, can we change the display of information on the figure image results? We may have spoken about this before and I thought otherwise, but now that I'm seeing it more in action we can eliminate the page title (I don't think it's clear what it is). And while you have the figure credit as a second meta item there, it would be better to include it as part of the excerpt, coming right after the caption, and have it be searchable too.

Sorry for the delay, made these updates but I hadn't realized the metadata wasn't searchable. Thankfully that was changed in the Pagefind beta, so I've updated to use that now.
