Add ggtb() support in Swing and Kotlin Notebook

[AndreiKingsley]

Now ggtb() is not supported in Swing and thus cannot be supported in Swing outputs in Kotlin Notebook. Now ggtb() doesn't have any effect with the default KTNB settings.

Temporary workarounds:
ggtb() should be used with Web render. In Kotlin Notebook, render can be switched from Swing to Web in two ways:

1. Globally
   In plugin settings, disable Render Kandy plots natively:

2. Locally
   In notebook code, disable swing rendering in letsPlotNotebookConfig notebook variable before plot display:

letsPlotNotebookConfig.swingEnabled = false
