Logged message to fix formatting violations is incorrect when applied to a composite build

[MariaSolOs]

If the plugin is applied to a composite build, the suggested command to fix spotless violations is incorrect.

E.g.: Consider the setup below.

my-composite
├── settings.gradle
├── build.gradle
└── my-utils
    ├── settings.gradle
    ├── build.gradle

If I apply this plugin in my-utils/build.gradle, a violation inside my-utils would be fixed by running ./gradlew :my-utils:spotlessApply. However this plugin suggests running :spotlessApply instead.
