Wrong link target in ModuleDescriptor#isAutomatic's API documentation

The API documentation of method isAutomatic() in class ModuleDescriptor links to the wrong modifier constant.

Line 1334 of ModuleDescriptor.java contains:

`... {@link Modifier#OPEN AUTOMATIC} modifier.`

It should read:

`... {@link Modifier#AUTOMATIC AUTOMATIC} modifier.`

to link to AUTOMATIC modifier.
