Fixed Unit Tests (BlockVector3.isLongPackable) (#1168)

* Fixed Unit Tests (BlockVector3.isLongPackable)

* Re-enable tests for ci

* Address gh action dependency complaints

* Fix "invalid usage of tag &" for MinecraftVersion.java

* Simple StubServer for BukkitWorldTest.java

* Add parallelgzip to test runtime, fixed javadoc encoding, make gradlew executable and patch StubServer for latest spigot / paper release

* Move Javadoc UTF-8 to PlatformConfig.kt

* Revert "make gradlew executable"
Was required for act to run, but not required for GH actions - Weird behavior

* Mark upstream changes, move class + apply editorconfig
