Rule for deleting lines between tags

[pun-ky]

as of fork config should delete forking related gradle files and contents, dedicated rules for deleting e.g

build.gradle.kts

// fork:start
fork {
    properties {
        /// this lines should not be available in forked project
    }
}
// fork:end

would be nice

this will allow to not having separate props.gradle.kts file and in consequence not having plugins defined under buildSrc in gradle-aem-single
