Documentation Suggestion: Classpath Setup Section

[BungTH]

Hello, I have been trying to integrate the liquibase plugin with my project and I ran into a problem when I got to the section: Setting up the classpath. After I try to add

buildscript {
	repositories {
		mavenCentral()
	}
	dependencies {
		classpath 'org.liquibase:liquibase-core:4.26.1'
	}
}

into my code, and updated the gradle, I got this error.

A problem occurred configuring root project 'cvup-back'.
> Could not resolve all files for configuration ':classpath'.
   > Could not find org.liquibase:liquibase-core:4.26.1.
     Searched in the following locations:
       - https://repo.maven.apache.org/maven2/org/liquibase/liquibase-core/4.26.1/liquibase-core-4.26.1.pom
       - https://plugins.gradle.org/m2/org/liquibase/liquibase-core/4.26.1/liquibase-core-4.26.1.pom
     Required by:
         project :

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

You can change the version required on the classpath to any other version that is available on the maven central repository here (I used 4.30.0 at the time of writing this issue, and it works fine!)
