Implement update notifications for Geyser

Geyser installations will now get notified when a new Bedrock release is out and Geyser must be updated. The system works similarly to ViaVersion where OPs get a notification of an update when they join. The permission node for players to see update notifications is `geyser.update` and the backing JSON that controls this can be found at https://github.com/GeyserMC/GeyserSite/blob/gh-pages/versions.json. There is also a config option to disable update checking.

This update also fixes modern Paper installations not being able to see colored text logged from Geyser in the console.
