plug-ins: Fix crash when exporting indexed HTML tables

Browse source 
Resolves #13122
The HTML table code expects RGB or Grayscale pixels
when creating a "BGCOLOR" attribute in the table.
This patch defines the capabilities of the exporter
in GimpExportOptions and retrieves a suitable image
with gimp_export_options_get_image ().
