[Brave News]: Add translations & icons for new Channels.

[fallaciousreasoning]

The Brave News backend has added some new channels (Music, Tech News, Tech Reviews & more). We should add translations for these new channels and also some new icons.

Thanks @aurangzaib048 for raising this!

@aguscruiz do you know if we have icons for these new channels?

I added the new channel icons here: https://www.figma.com/file/SDcE22eeUsV2uc4dy3NwaC/Desktop-News---Onboarding?node-id=740%3A67478&t=vhDSgWnpqXnw0PbI-1

Let me know if we're missing any

New channels as best I can tell are:

• Entertainment News
• Film and TV
• Music
• Regional News
• Tech News
• Tech Reviews
• US News

I think we missed Entertainment News, but I'm just going to reuse the entertainment icon.
