Make template set root directories accessible for the reader

[jan-vcapgemini]

Currently we determine the folder for the template set utilities like this:

cobigen/cobigen/cobigen-core/src/main/java/com/devonfw/cobigen/impl/config/TemplateSetConfiguration.java

Lines 187 to 196 in ac2efa9

	/**
	* Gets the source folder for utility classes
	*
	* @return the source folder where utility classes are located
	*/
	private Path getUtilSourceFolder(Path path) {
	// TODO: replace with proper root template set folder
	return path.getParent().getParent().getParent().getParent();
	}

Adjust the TemplateSetConfigurationManager here:

cobigen/cobigen/cobigen-core/src/main/java/com/devonfw/cobigen/impl/config/reader/TemplateSetConfigurationManager.java

Lines 75 to 82 in ac2efa9

	List<Path> templateSetDirectories = retrieveTemplateSetDirectories(configRoot);
	for (Path templateDirectory : templateSetDirectories) {
	Path templateSetFilePath = templateDirectory.resolve(ConfigurationConstants.MAVEN_CONFIGURATION_RESOURCE_FOLDER)
	.resolve(ConfigurationConstants.TEMPLATE_SET_CONFIG_FILENAME);
	addConfigRoot(templateSetFilePath, templateDirectory, this.templateSetPaths);
	}

to get access to the root directory of each template-set.
