Upgrade to Scenes v6

Problem

We were on @grafana/scenes and @grafana/scenes-react v5.42.0, while v6 has been available for some time with new features and improvements including internationalization support.

Solution

This PR upgrades both packages to v6.52.10, bringing:

• Enhanced internationalization support via i18next
• 10+ minor versions of accumulated features and bug fixes
• Improved APIs and components from the Scenes team

Changes

• Upgraded @grafana/scenes from 5.42.0 to 6.52.10
• Upgraded @grafana/scenes-react from 5.42.0 to 6.52.10
• Updated yarn.lock with new dependencies

Bundle Size Impact

⚠️ This PR increases the bundle size by ~461 KB (~18%)

@ckbedwell The ~461 KB bundle size increase (~18%) seems to come entirely from upgrading @grafana/scenes and @grafana/scenes-react from v5.42.0 to v6.52.10 by looking at the webpack-bundle-analyzer, it seems to be due to the addition of i18next internationalization support and 10+ minor versions worth of accumulated features and enhancements 😕
