Support CVE test

[derevnjuk]

Add support for the cve_test test type to enable the "Common Vulnerability Exposure (CVEs)" vulnerabilities.

To run this test, it should be possible to use the following code snippet:

[Fact]
public async Task Get_Users_ShouldNotFindCVEs()
{
  var target = new Target($"{_fixture.Url}/Users")
    .WithMethod(HttpMethod.Get);

  var builder = new ScanSettingsBuilder()
    .WithName(nameof(Get_Users_ShouldNotFindCVEs))
    .WithTests(new List<TestType> { TestType.Cve });

  await _runner
    .CreateScan(builder)
    .Run(target);
}
