Closes #7927 .

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.

LGTM - seems pretty straightforward! I'll get started on upstreaming this.

It looks like this ended up breaking all the DataprocCluster tests that don't define an explicit temp bucket, since the server then assigns one for you. (For example, TestAccDataprocCluster_singleNodeCluster.)

The fix for this should be to mark the field as Computed as well as optional. That should still allow setting an explicit value while also accepting whatever the server sends back if there's not a value defined.

LGTM and tests are passing

I noticed the comment in magic-modules, but it's been quiet for a while. Should I just wait or shall I remove the test that's suggested there? Your interpretation was correct, by the way, I copied some tests to ensure they also pass with this temporary bucket.

@bartcode thanks for checking back in. I lost track of this, sorry. Let me ping Sam.

[melinath]

Okay, so there's just one thing to change - since this is a handwritten resource, the docs also need to be updated manually. They're in website/docs/r/. Thanks!

[bartcode]

Thanks! I wasn't aware of those docs, but they should be in order now!
