Add support for a new Minecraft version

1. Create a new branch for the new version (e.g. update/1.20.6)
2. Create a new viaforge-mc<version> folder in the root directory of the project
3. Add a gradle.properties file with the forge_version set (Available at https://files.minecraftforge.net/)
4. Register it inside the settings.gradle file
5. Copy the code from the previous version and update it accordingly

Build logic

The build.gradle file contains the shared build code for all submodules. Build code for only specific versions of the game can be wrapped with checks using the versionId integer which will be parsed from the forge_version.

An example would be:

if (versionId >= 1_13_2) {
    // We don't need to package mixins into Forge 1.13+ jars, since Forge already has it
    exclude("org/spongepowered/**")
}

Notes

Shared source code is inside the src/main/java root folder, while version-specific code is inside the /viaforge-mc<version> folders.
