 Background: #16917, #33381, #46594, #51043.

 Per discussion in #51043, specifically comment:16:ticket:51043 and
 comment:26:ticket:51043, for WordPress to consider dropping support for
 PHP 5.6 or 7.0, these versions need to get below 5% usage, regardless of
 the WordPress version used on those sites.

 As of 17 Dec 2022, that happened:
 * PHP 5.6 is at 4.99% of all WordPress sites
 * PHP 7.0 is at 2.68%
 * PHP 7.1 is at 1.82%

 Per discussion with @azaozz, this means we can bump the minimum required
 PHP version to 7.2, and start preparations for bumping it to 7.4 in the
 foreseeable future.

 This ticket aims to determine the specific minor PHP version in the 7.2
 branch to bump to, as well as to track any other tasks related to the
 bump.

 Previously:
 * #46594 Bumping the minimum PHP version to 5.6 in WordPress 5.2
 * #16917 Bumping the minimum PHP version to 5.2 in WordPress 3.2
