Bug Description

When running a Spigot server, the adventure API is obviously missing.
Some plugins will implement the AdventureAPI, which can cause some issues.
For example, in ch.njol.skript.bukkitutil.sounds.SoundReceiver there is this field:
boolean ADVENTURE_API = Skript.classExists("net.kyori.adventure.sound.Sound$Builder");

If another plugin has implemented AdventureAPI, this will result in this field being true.
But when running the play sound effect, we get the following error:
IncompatibleClassChangeError: Class org.bukkit.SoundCategory does not implement the requested interface net.kyori.adventure.sound.Sound$Source$Provider
That is because the Bukkit class doesn't implement the adventure class (that paper does)

Expected Behavior

For the error to not happen, and the sound to play!

Steps to Reproduce

1. start up a server on Spigot
2. make sure to have another plugin with AdventureAPI implemented (I can provide one if need be)
3. Login
4. run play sound, ex: play sound "test"
5. get error
6. profit!

We might be able to try some different checks, but I would think that any plugins shading Adventure API ought to relocate it.
