Drop libvte9 suggestion

[Egmont Koblinger]

Geany recommends to install libvte9.

Since Bionic, Geany has been compiled against GTK3. libvte9 uses GTK2. Hence I'm pretty sure geany cannot make any use of it.

Please remove this outdated suggestion, or replace by the GTK3 based libvte-2.91-0 if geany can use this latter one (which I'm not sure about). Thanks!

I've fired up Geany, and clicked on Terminal in the bottom left corner.

The presented terminal is libvte-2.91-0, as confirmed by `echo $VERSION` reporting its version number.
