fix: set owner name and email to "default"

Closes coder/modules#162

When the terraform plan is run, the `data.coder_workspace.me.owner_email` and `data.coder_workspace.me.owner_name` fields are blank, which causes the template build to fail. 

This should resolve the issue by setting those entries to a non-empty string.
