REST API: Log doing_it_wrong notices to debug.log

[ilclaudio]

Fixes #64260. The doing_it_wrong_trigger_error filter was preventing all doing_it_wrong notices from being logged during REST requests. This change ensures notices are written to debug.log while still preventing trigger_error() from interfering with REST responses.

Now the error is filterd but in the debug.log file you can see a meeesage like this:

[21-Nov-2025 14:01:41 UTC] REST API - Doing it wrong: register_rest_route - The REST API route definition for test/v1/example is missing the required permission_callback argument. For REST API routes that are intended to be public, use __return_true as the permission callback. (This message was added in version 5.5.0.)

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.

Test this pull request with WordPress Playground.

It looks like one of the GitHub Actions jobs failed due to a transient network issue (curl error 7 while downloading from packagist.org) and not because of my code changes.
Could someone please re-run the failed job? Thank you!

Will it, though? During REST API responses, the PHP display_errors config option is set to 0:

wordpress-develop/src/wp-includes/load.php

Lines 638 to 647 in 3d811f2

	/*
	* The 'REST_REQUEST' check here is optimistic as the constant is most
	* likely not set at this point even if it is in fact a REST request.
	*/
	if ( defined( 'XMLRPC_REQUEST' ) || defined( 'REST_REQUEST' ) || defined( 'MS_FILES_REQUEST' )
	|| ( defined( 'WP_INSTALLING' ) && WP_INSTALLING )
	|| wp_doing_ajax() || wp_is_json_request()
	) {
	ini_set( 'display_errors', 0 );
	}

Therefore, why not just remove the doing_it_wrong_trigger_error filter altogether?

Re-run!
