SpongeGradle 2.0.0 is considered outdated

[vintprox]

• Minecraft Development plugin for Intellij version: 2021.3-1.5.18-314
• IntelliJ version: 2021.3.2
• Operating system: Ubuntu 20.04.4
• Target platform: SpongeVanilla, SpongeAPI 8

"Minecraft Development" plugin for Intellij generates a convenient runServer task in my project.

This is the log I get after running runServer task with valid plugin project:

01:32:53: Executing 'runServer'...

Under further inquiry from the maintainer of SpongeGradle, it turns out that I use an "outdated SpongeGradle version".

All it took to get stuff working is changing 2.0.0 to 2.0.1, and it done like a charm:

plugins {
    `java-library`
    id("org.spongepowered.gradle.plugin") version "2.0.1"
}

I should warn that API version of SpongeAPI being targetted is 8, so it may be not a requirement for older versions to run smoothly.

Nevertheless, I think that few templates here could use some updating:

• Sponge 8+ build.gradle.kts.ft
• Sponge 8+ Submodule build.gradle.kts.ft
