Match preview versions in google_composer_environment regex

[rileykarson]

Resolves a test error: Error: "config.0.software_config.0.image_version" ("composer-1.17.0-preview.0-airflow-2.0.1") doesn't match regexp "composer-([0-9]+\\.[0-9]+\\.[0-9]+|latest)-airflow-([0-9]+\\.[0-9]+(\\.[0-9]+.*)?)"

New string is composer-1.17.0-preview.0-airflow-2.0.1, we expected strings like composer-1.4.1-airflow-1.10.0 and composer-latest-airflow-1.10.0.

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.

It looks like unit tests are failing - could you also add a unit test for a value that would be expected to pass with the new regex but was previously failing?

Done, pushed a change.
