doc: adapt features tables header height

The length of the longest header name is used to adjust the padding
of the header row automatically, instead of fixed length.
The previous length (10) was too short for vdev_netvsc.

Fixes: 6086ab3bb3d2 ("net/vdev_netvsc: introduce Hyper-V platform driver")
