This pull request updates region tags in several files within the appengine/websockets sample. The changes are straightforward and correctly address the specified bugs. The commit messages clearly explain the changes, and the code follows the project's style guidelines. I've referenced the Samples Style Guide in this review.

Here's a summary of the style guide elements I've checked:

• Region tags: The new region tags are correctly placed and formatted.
• Comments: The existing comments are clear and concise.
• Consistency: The changes maintain consistency with the rest of the codebase.

Overall, the changes are well-done and improve the accuracy of the sample code. The checklist items from the pull request template should be reviewed before merging.

Per the Samples Style Guide, it's best to remove the old region tags when they are no longer used. Since gae_websockets_app replaces appengine_websockets_app, the latter can be removed.

Suggested change

	// [START gae_websockets_app]
	// [START appengine_websockets_app]
	// [START gae_websockets_app]
	const app = require('express')();
