AudioPlayer to CustomDiscs

• Fix a little bug in the AutoConvertJukeBox where it applied the Tooltip Display to all discs even vanilla discs.
• Also fix the building process (version wasn't "updated" on release 1.1.5)

This release is meant to align with the next release of CustomDiscs 5.2.0 which will use PacketEvents !

Changelog :

• Update Gradle Shadow to 9.3.2
• Remove ProtocolLib as dependency
• Add PacketEvents as dependency (replacing ProtocolLib)
• Fixed a little bogus code missed in previous releases.

Update 1.1.4

• Add Discord invite link inside the plugin help message.
• No other change on that release.

Update 1.1.3

• Add default mob heads/skulls to the allowed convertible list
• Update Gradle Shadow to release 9.3.1

For the default mob heads/skulls to actually play, an update for CustomDiscs will be needed (version not yet released, planned for v5.1.5 soon)

• Update CommandAPI to stable release 11.1.0
