network_site_info_form action missing in site-info.php

[virgodesign]

Hi,
in the network administration, wordpress 4.5 introduced a new action in site-new.php that let users perform custom actions within the "new site creation" form.

The action is the following

/**
 * Fires at the end of the new site form in network admin.
 *
 * @since 4.5.0
 */
do_action( 'network_site_new_form' );

One possible action to perform is, for example, add custom meta field to the new registered site.

As of wp 5.1 the support for site metadata as taken a big step further with the new db table wp_blogmeta.

In the site-info.php network admin screen there is no chance to display any custom fields created using for example the network_site_new_form previously introduced, nor any type of site metadata created by a super admin.

The missin key in this flow is an action that let users display/add custom fields in the site-info.php network admin screen.

I would like to propose to add the following action hook in site-info.php just before the submit_button() function:

/**
 * Fires at the end of the site info form in network admin.
 *
 * @since 5.5.1
 * 
 * @param int $id The site ID.
 */
do_action( 'network_site_info_form', $id );

Hi there, welcome to WordPress Trac! Thanks for the ticket.

Adds a new action. Needs mention in Misc Dev Note.

In 49199:

Networks and Sites: Introduce network_site_info_form action.

The action fires at the end of the site info form in network admin, and complements the existing network_site_new_form action.

Props virgodesign.
Fixes #50704.
