Update metadata for the external rules

[alex-sonar]

Fixes #3126

[yassin-kammoun-sonarsource]

Let's add a unit test in the following integration test that asserts that we properly import external issues from a couple of ESLint plugins:

SonarJS/its/plugin/tests/src/test/java/com/sonar/javascript/it/plugin/EslintReportTest.java

Lines 39 to 56 in 622c9ef

	class EslintReportTest {
	private static final Orchestrator orchestrator = OrchestratorStarter.ORCHESTRATOR;
	private static final String PROJECT_KEY_PREFIX = "SonarJS-eslint-report-test";
	private static final File PROJECT_DIR = TestUtils.projectDir("eslint_report");
	@Test
	void should_save_issues_from_external_report_with_relative_paths() {
	String projectKey = PROJECT_KEY_PREFIX + "-relative";
	SonarScanner build = OrchestratorStarter
	.createScanner()
	.setProjectDir(PROJECT_DIR)
	.setProjectKey(projectKey)
	.setProjectName(projectKey)
	.setProjectVersion("1.0")
	.setSourceDirs("src");

Right now, it seems that we are only testing with ESLint core rules given the content of this report:

SonarJS/its/plugin/projects/eslint_report/report.json

Lines 1 to 11 in 622c9ef
