Fix create isssue for container scanning from dashboard issue

What does this MR do?

Fixes https://gitlab.com/gitlab-org/gitlab-ee/issues/13676

Problem occurs when we try to create issue for container scanning vulnerability using security dashboard.

we use sprintf to format ticket content however sprintf doesn't work well with the HashWithIndifferentAccess i.e

data = {"name" => "can"}

sprintf("%{name}", data} ==> this will fail

data = {name: "can"}

sprintf("%{name}", data} ==> this is okay
