Update applications.json (#3405)

Per this article (https://www.engadget.com/ai/the-browser-company-stops-active-development-of-arc-in-favor-of-new-ai-focused-product-153045276.html) Arc Browser is no longer in active development. Should be considered abandonware and removed. (Another article recommends Zen as an alternative which is already in the list of applications)
