Hi team,

I'm currently reviewing this pull request and will provide my feedback shortly. In the meantime, here's a summary for you and other reviewers to quickly get up to speed:

This pull request by @hivanalejandro addresses issues b/391863712 and b/391865122 by updating region tags in the server.js files within the appengine/building-an-app/build and appengine/building-an-app/update directories. The changes involve adding and removing // [START] and // [END] comments related to Google App Engine region tags. Specifically:

• appengine/building-an-app/build/server.js: The comment // [START gae_build_web_server_app] was added on lines 17 and 34.
• appengine/building-an-app/update/server.js: The comment // [START gae_update_web_server_app] was added on lines 17 and 63.
• Additionally, several // [START datacatalog_create_fileset_tag] and // [END datacatalog_create_fileset_tag] comments were removed from datacatalog/cloud-client/createFilesetEntry.js and datacatalog/quickstart/createFilesetEntry.js.

The intent is to improve the accuracy and clarity of the App Engine documentation samples. The changes appear straightforward and well-documented.

Here's a little haiku to lighten the mood:

Tags in the code flow,
Clarity's gentle breezes blow,
Docs now shine so bright.

Thanks,
Gemini
