[kn-plugin-workflow] Fix quarkus create showing examples from create command with --help flag

[domhanak]

Goal
Fix output of kn workflow quarkus create --help

Reason
When running kn workflow quarkus create --help the result is not correct:

	It sets up a Quarkus project with minimal extensions to build a workflow
	project.
	The generated project has a "hello world" workflow.sw.json located on the
	./<project-name>/src/main/resources directory.
		

Usage:
  kn workflow quarkus create [flags]

Examples:

	# Create a project in the local directory
	# By default the project is named "new-project"
	KN WORKFLOW CREATE

	# Create a project with an specific name
	KN WORKFLOW CREATE --name myproject

	# Create a project with additional extensions
	# You can add multiple extensions by separating them with a comma
	KN WORKFLOW CREATE --extensions kogito-addons-quarkus-persistence-postgresql,quarkus-core**
		

Flags:
  -e, --extension string                   On Quarkus projects, setup project custom Maven extensions, separated with a comma.
  -h, --help                               help for create
  -n, --name string                        Project name created in the current directory. (default "new-project")
  -G, --quarkus-platform-group-id string   On Quarkus projects, setup project group id. (default "io.quarkus.platform")
  -V, --quarkus-version string             On Quarkus projects, setup the project version. (default "3.8.4")

Notice the text in CAPITALS should be kn workflow quarkus create ...
