doc: add example to ImportOrder about other groups #5982
Description
noticed at #5972 (comment)
We need to put this to documentation as it is not obvious.
The code is
import static java.io.File.listRoots;
import static javax.swing.WindowConstants.*;
import static javax.swing.WindowConstants.*;
import static java.io.File.createTempFile;
import static java.io.File.pathSeparator;
import static com.puppycrawl.tools.checkstyle.checks.imports.avoidstaticimport.InputAvoidStaticImportNestedClass.InnerClass;
import static com.puppycrawl.tools.checkstyle.checks.imports.avoidstaticimport.InputAvoidStaticImportNestedClass.InnerClass.one;
when staticGroups="" mean one group, the imports com... should be before java...
The violation is reported.
when staticGroups="java, org" there actually three groups: java*, org* and * (everything else).
In this case, the imports com... should be in the last group. No violation here.
