Subject: [PATCH] Add input to the test Gutenberg build workflow.

This adds a new input for the reusable workflow responsible for testing the Gutenberg build script to allow branches to use  a specific branch in the `gutenberg` repository.

This allows for a similar pattern to that used in the end to end testing workflow where a specific version of the Gutenberg plugin is pinned once support for the branch of WordPress running the workflow is dropped.
