Incompatible with Apple Silicon

[FalcoG]

J2V8 does not seem to work for Apple's M1 arm64.

$ npm run serve results in the following error:

Apparently j2v8 has dropped support for macOS altogether: https://github.com/eclipsesource/J2V8/issues/556#issuecomment-896128464

Tried to run it with the following java builds:

% java --version
openjdk 17.0.2 2022-01-18 LTS
OpenJDK Runtime Environment Zulu17.32+13-CA (build 17.0.2+8-LTS)
OpenJDK 64-Bit Server VM Zulu17.32+13-CA (build 17.0.2+8-LTS, mixed mode, sharing)

% java --version
openjdk 17.0.2 2022-01-18
OpenJDK Runtime Environment Homebrew (build 17.0.2+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.2+0, mixed mode, sharing)

Found a possible alternative for J2V8: https://github.com/caoccao/Javet/. Maybe this will also make it easier to fix https://github.com/customrealms/bukkit-runtime/issues/8.
