Remove extra quotes when calling rake task

What does this MR do and why?

Describe in detail what your merge request does and why.

Remove extra quotes when calling rake task. As can be seen in the job logs (https://ops.gitlab.net/gitlab-org/release/tools/-/jobs/6760032), the quote becomes part of the value, which causes the QA to never be created.
