Describe the bug
It appears that the deploy process for the multi-cluster engine expects a file that doesn't exist. I followed the directions in the README.md

To Reproduce
Steps to reproduce the behavior:

1. Log into the cluster using oc login and token obtained from the console
2. Run ./start.sh
3. Provide 2.0-latest as the SNAPSHOT TAG
4. The installation fails because of a missing file

Expected behavior
I'd expect the multi-cluster operator to be installed.

Screenshots

$ ./start.sh
* Testing connection
* Using baseDomain: router-default.lbragstad-dev.devcluster.openshift.com
* oc CLI Client Version: 4.10.6
