Update central plugin repository

[kastork]

the gradle dependencyUpdates task reports version 1.2.4 is available.

The following dependencies have later milestone versions:
 - uk.co.cacoethes:lazybones-gradle [1.2.3 -> 1.2.4]

But when I update my build to use it:

plugins {
    id "uk.co.cacoethes.lazybones-templates" version "1.2.4"
    id 'com.github.ben-manes.versions' version '0.11.3'
}

The build errors out with:

* What went wrong:
Plugin [id: 'uk.co.cacoethes.lazybones-templates', version: '1.2.4'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Gradle Central Plugin Repository (plugin 'uk.co.cacoethes.lazybones-templates' has no version '1.2.4' - see https://plugins.gradle.org/plugin/uk.co.cacoethes.lazybones-templates for available versions)

I think this has something to do with the changes the Gradle team made to the way plugins are published. Bintray is hosting the 1.2.4 version, but that isn't visible via the plugin portal for some reason.

The workaround is to use the "all Gradle versions" code snippet shown on the plugin portal page for lazybones-gradle, substituting 1.2.4 for 1.2.3.
