Ignore volatile state field in Notebooks Instance ISVs

Caused a test failure last night

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.

No idea what's up with VCR- it's failing on mechanical stuff, and that failure cancels the test/lint steps. I started https://ci-oss.hashicorp.engineering/buildConfiguration/GoogleCloudBeta_ProviderGoogleCloudBetaMmUpstream/215445?buildTab=overview instead, as this seems like a random occurrence on this PR.

Heya Riley, is this still relevant ?
