Note that RISE servers are not compatible with vRack

[jefft]

I have just had confirmed with tech support that bare metal rise servers (https://www.ovhcloud.com/en-au/bare-metal/rise/) cannot be added to a vRack.

This fact is not mentioned in the documentation. May I suggest that this line:

docs/pages/cloud/dedicated/vrack_configuring_on_dedicated_server/guide.en-au.md

Line 23 in 7eb4d4d

- Two or more [dedicated servers](https://www.ovhcloud.com/en-au/bare-metal/) (compatible with vRack)

be expanded to: "Note that RISE dedicated servers are not compatible".
