Release the package to Maven Central or equivalent instead of self hosted for backup

Hi, just to say you're doing a very great job, but your server is inaccessible sometimes and I'd like to have a setback available.

I will see if I can publish it to a JCenter repository too.

Give you a feedback late this week.

Hi @stevefan1999-personal, I finally publish a backup repository for KotlinBukkitAPI, I'm using oss.frog.org. Hope this help you!

repositories {
  maven("https://oss.jfrog.org/oss-snapshot-local/")
  maven("http://nexus.okkero.com/repository/maven-releases/") //skedule
  maven("https://repo.codemc.org/repository/maven-public") //bstats
}
