Update virtual-network-service-endpoints-overview.md

[bjompen]

Removed double images.
The VNet_Service_Endpoints_Overview image was doubled in the article, once using markdown standard, and once using other.
On learn both was rendered the same and two exact images is seen, on github / md render one image and one html blob is seen.

@bjompen
Made suggested change and I will sign off. The one removed is the one we use for our standard, the one left is the old one and should be removed.

[bjompen]

Done, changed the one kept as per request.
