Use DuckDuckGo for search and fix typo in remove history dialogue

[cortadocodes]

Hi @alexmercerind, thanks for your work creating Audire! I love the app and noticed a couple of things I wanted to suggest as a change (up to you of course though):

• Switching to DuckDuckGo for music search instead of Google - this would be great as Audire seems to be a privacy-friendly FOSS app, so it would be great to use a private search engine. I considered Brave Search too but wondered if it was too niche at this point
• I noticed the word "remove" was missing in the "remove history" dialogue so I added it in

Let me know what you think!

LGTM!

Thanks a lot.
