The Approve button of JFileChooser in CUSTOM_DIALOG mode has no tooltip in Aqua L&F.

Other L&Fs set the tooltip.
Aqua L&F should be consistent with other Look-and-Feels.

The attached FileChooserApproveButtonTooltip.java produces the following output:

Metal - Open - Open selected file
Nimbus - Open - Open selected file
CDE/Motif - OK - Open selected file.
Mac OS X - Choose - null

This is on the build with the fix for JDK-8299522 which is currently on review https://github.com/openjdk/jdk/pull/11901#pullrequestreview-1253170424 and with the integrated fix for JDK-8300084.

Without the above prerequisites, the button text and tooltips are null; without JDK-8300084, a NullPointerException is thrown in Aqua L&F.
