Hi team,

I'm currently reviewing this pull request and will provide a full review shortly. In the meantime, here's a summary to help you and other reviewers quickly understand the changes:

This pull request, submitted by @hivanalejandro, aims to migrate the region tag in the nodejs-docs-samples repository's datacatalog quickstart sample. Specifically, it addresses issue b/389763067.

The changes involve updating the createFilesetEntry.js file:

• The old region tag datacatalog_create_fileset_quickstart_tag is replaced with the new tag data_catalog_create_fileset_quickstart_tag.
• This change is reflected both at the beginning and end of the main function (lines 29-30 and 128-129 respectively).

The author has indicated that all tests and linting checks have passed. The checklist in the PR description confirms this.

I'll provide a more detailed review shortly, but this summary should give everyone a good overview of the changes.

A little poem to brighten your day:

Tags shift, a code's new hue,
A region's name, refreshed and true,
Bugs flee, the fix is done.

Best,
