Renamed Flat*Laf.install() methods to Flat*Laf.setup() to avoid confusion
with UIManager.installLookAndFeel(LookAndFeelInfo info). The old
Flat*Laf.install() methods are still there, but marked as deprecated. They
will be removed in a future version. https://github.com/JFormDesigner/FlatLaf/releases/tag/1.2
