false code example

[ThomasUllrich666]

the code example on this page is wrong. page: https://cloud.ibm.com/docs/vpc?topic=vpc-configuring-the-security-group&interface=cli

code example: ibmcloud is instance-create test-instance $vpc us-south-2 b-4x16 $subnet 1000 --image $image --keys $key --security-groups $sg

parameter --security-groups not existent and needs to be replaces with sgs
