Should be 20251202

Suggested change

	wp_enqueue_style( 'twentytwelve-block-style', get_template_directory_uri() . '/css/blocks.css', array( 'twentytwelve-style' ), '20251101' );
	wp_enqueue_style( 'twentytwelve-block-style', get_template_directory_uri() . '/css/blocks.css', array( 'twentytwelve-style' ), '20251202' );

These blocks stylesheets usually have a version string on the last modified date, and r61107 was the most recent change for Twenty Twelve's. And according to UTC, the date was still 20251031 for 87 minutes :)

Ultimately, these just need to be strings that no sites should have used yet.

Test using WordPress Playground

The changes in this pull request can previewed and tested using a WordPress Playground instance.

WordPress Playground is an experimental project that creates a full WordPress instance entirely within the browser.

Some things to be aware of

• The Plugin and Theme Directories cannot be accessed within Playground.
• All changes will be lost when closing a tab with a Playground instance.
• All changes will be lost when refreshing the page.
• A fresh instance is created each time the link below is clicked.
• Every time this pull request is updated, a new ZIP file containing all changes is created. If changes are not reflected in the Playground instance,
  it's possible that the most recent build failed, or has not completed. Check the list of workflow runs to be sure.

For more details about these limitations and more, check out the Limitations page in the WordPress Playground documentation.

I'm not ready to do a thorough review, but I have two comments.

• r60934 added package.json and package-lock.json files to Twenty Twenty-Two and Twenty Twenty-Five, and those also need updates to the version number.
• Twenty Twenty-Three still has no code changes since 1.6. That theme might only have the "Tested up to" version bump, as in r60158, again without packaging a new theme.
