CustomDiscs

This Beta release introduce the following changes :

• Update Gradle Shadow to release 9.3.1
• Add default mob heads/skulls to the allowed list to be played
• Reorder checks for HopperManager + use of local variable to avoid excessive external calls (shouldn't change a lot "performance wise", but still a little better this way)
• Fix : Mining head/skull to keep its custom data.
• Fix : Breaking noteblock and/or head (by hand or explosion) stop any playing audio.
• Fix : Triggering a noteblock (redstone or by hand) restart the head custom audio.

Known limitation/"bug" :
