 Site Health: Add Intl to the list of recommended PHP extensions.

 **Why is the PHP Intl extension important?**

 WordPress is a global, international software, with support for a
 multitude of languages and with infinite combinations. Approximately half
 of the installations are in a language that is not the default (English),
 and this leads us to think about localization, transliteration, encoding
 conversions, calendar operations, collation… in short, everything you have
 with the different languages and formats that are around the planet. And
 this is what the [https://www.php.net/manual/en/intro.intl.php PHP Intl
 extension] provides.

 **What do we as the WordPress Community gain from this extension?**

 This extension provides a lot of functions for better internationalization
 support, including but not limited to:
 * [https://www.php.net/manual/en/collator.compare.php collator_compare()]
 to compare Unicode text strings
 * [https://www.php.net/manual/en/numberformatter.format.php
 numfmt_format()] to format a number according to the selected locale
 * the [https://www.php.net/manual/en/normalizer.normalize.php
 normalization] of characters
 * the [https://www.php.net/manual/en/messageformatter.formatmessage.php
 formatting] of messages
 * getting the
 [https://www.php.net/manual/en/intlcalendar.getfirstdayofweek.php first
 day of the week] according to the locale.


 In addition to functionality and ease of development, the extension can
 also help improve security, with classes like `Spoofchecker` that can tell
 you [https://www.php.net/manual/en/spoofchecker.areconfusable.php if
 ‘google.com’, ‘goog1e.com’ can confuse the user], or functions related to
 Internet domains, both to convert an
 [https://www.php.net/manual/en/function.idn-to-ascii.php IDN domain to
 text] and [https://www.php.net/manual/en/function.idn-to-utf8.php text to
 IDN].

 **Hosting Team Recommendation**

 Taking into account that WordPress continues to grow, the Hosting Team has
 considered a good recommendation, but not an obligation, for all hosts
 that work with WordPress to offer this extension, by default, to all
 users.
