Support for Brave Search

Description

I would like to take this addition on myself. I will submit a PR for this.

This feature would add Brave search to the list of search engines that are able to be used. I don't believe there are any downsides to this, it's simply adding search.brave.com/search?q={QUERY}. This would add a new option for the search engine to use in the search widget.

You can set the search engine in your config to exactly that without it needing to be built into Glance:

search-engine: https://search.brave.com/search?q={QUERY}
