Fix stray Go 1.19.0 lint error

[rileykarson]

Followup to https://github.com/GoogleCloudPlatform/magic-modules/pull/6398, not sure how it snuck through as I'd ran make lint locally to check for deltas!

If this PR is for Terraform, I acknowledge that I have:

• [ ] Searched through the issue tracker for an open issue that this either resolves or contributes to, commented on it to claim it, and written "fixes {url}" or "part of {url}" in this PR description. If there were no relevant open issues, I opened one and commented that I would like to work on it (not necessary for very small changes).
• [ ] Generated Terraform, and ran make test and make lint to ensure it passes unit and linter tests.
• [ ] Ensured that all new fields I added that can be set by a user appear in at least one example (for generated resources) or third_party test (for handwritten resources or update tests).
• [ ] Ran relevant acceptance tests (If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know).
• [ ] Read the Release Notes Guide before writing my release note below.
