Fixes hashicorp/terraform-provider-google#12102

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.

Your assigned reviewer will help review your code by:

• Ensuring it's backwards compatible, covers common error cases, etc.
• Summarizing the change into a user-facing changelog note.
• Passes tests, either our "VCR" suite, a set of presubmit tests, or with manual test runs.

You can help make sure that review is quick by running local tests and ensuring they're passing in between each push you make to your PR's branch. Also, try to leave a comment with each push you make, as pushes generally don't generate emails.

If your reviewer doesn't get back to you within a week after your most recent change, please feel free to leave a comment on the issue asking them to take a look! In the absence of a dedicated review dashboard most maintainers manage their pending reviews through email, and those will sometimes get lost in their inbox.

LGTM- updated the changelog entry as adding update support to an existing field's an enhancement rather than a bug (but is often filed by users as a bug, which is pretty fair)
