JDKs installed by asdf are not discovered.

Affected version

3.2.0

Bug description

The plugin does not find JDKs installed by asdf.

The problem, I believe, is here:

        installedDirs.add(userHome.resolve(".asdf").resolve("installs"));

should be replaced with:

        installedDirs.add(userHome.resolve(".asdf").resolve("installs").resolve("java"));
