v4.0.0

At long last, a stable release of adventure-platform.

This release requires Adventure 4.9.1 and is compatible with:

• Legacy Bukkit and Spigot servers, from 1.17.1 all the way back to 1.7.10 (with some features unsupported in earlier versions)
• Legacy BungeeCord servers
• SpongeAPI 7

While more modern platforms that implement Adventure natively such as SpongeAPI 8+, Velocity, and Paper 1.16.5+ are preferred, adventure-platform is being released as a migration tool for those who cannot exclusively target those platforms yet.
