Improvements and updated for browser_mod 2

It's been a while, but here is finally a new version of the FR24 card. In this version, the popup has been modified based on the modified version of browser_mod and some minor improvements have been made to the notifications that appear when there are no (good) data has been found.

⚠️ Note if you use the popup option: this update is not compatible with old versions of browser_mod. If you don't want to update browser_mod, that's fine, but unfortunately you can't use this update either.

Many thanks to @BrettEBowman and @masterfish1 for testing the pre-releases! 👏 And of course to @AlexStephenLytton for updates in the German language file.

Full Changelog: v0.5.2...v0.6.0
