[Feature Request] add option to search Arc Browser favorites

[BrunoTassinari]

I would really like to have integration with Arc browser, searching for favorites is the feature I use most lately. It would be really good

Ueli v9 (alpha releases are available here) already supports Arc Browser bookmarks.

Edit: I changed the title of this PR to "add option to search Arc Browser favorites" as the Browser Bookmarks extension already supports Arc Browser bookmarks.
