Always Open “Watch in Youtube” links in a new tab. This fixes a lot of back-forward navigation with DuckPlayer in the same tab, incluiding the task above

Steps to test this PR:

• 1. Go to Settings > DuckPlayer
• 2. Disable “Open Duck Player in a new tab, whenever possible”
• 3. Enable “Always open Youtube videos in Duck Player"
• 4. Go to https://www.youtube.com/@mkbhd
• 5. Open a Video, which should open in Duck Player and make sure it’s playing
• 6. Click “Watch in Youtube” button at the bottom.
• 7. Confirm the video opens in a new tab, and the previous video pauses.
• 8. Hit the back button, and confirm the newly opened tab is closed and you’re back to the paused video.
