trailing whitespace added after Background: in each feature file

[Jiehong]

Creating this bug report, because I'm not sure if it's link to spotless or this plugin.

Spotless issue is: https://github.com/diffplug/spotless/issues/1693

[Jiehong]

issue is confirmed to come from this repository: when running mvn spotless:apply, this plugin is adding a trailing whitespace:

Creating a feature file with the following content:

Feature: my_feature

  Background:
    def thing = "hello"

and running mvn spotless:check will generate the following error:

[ERROR] Failed to execute goal com.diffplug.spotless:spotless-maven-plugin:2.36.0:check (default-cli) on project maestro_server_qa_karate: The following files had format violations:

Note the trailing space added after Background:.

The code here naively assumes that all backgrounds, (and presumably all scenarios and examples too) have a name. Happy to take a pull requests that updates the tests and fixes this.
