QA issue for auto-deploys should reference testing on staging-canary
As part of epic we re-arranged the deployment pipeline for GitLab.com. With the re-arrangement, the first environment deployed to (and most important environment to test) is staging-canary, not staging.
QA issues as part of auto deploy (e.g. https://gitlab.com/gitlab-org/release/tasks/-/issues/3664#escalating-high-severity-regressions) still reference staging as the first place to test and find regressions. We should update this to reference staging canary instead and make sure people are aware of how to access it https://about.gitlab.com/handbook/engineering/infrastructure/environments/canary-stage/#accessing-the-canary-stage-of-an-environment
