Remove php8.0 variants as it has reached end of life

[yosifkit]

See also https://www.php.net/supported-versions.php + https://github.com/docker-library/php/pull/1463

This also moves the default PHP version from 8.0 to 8.2 since it is just as supported; see wordpress.org hosting handbook:

WordPress supports many versions of PHP, some even obsolete (PHP Compatibility and WordPress Versions), for hosting companies we recommend: WordPress 6.4

• PHP 8.1
• PHP 8.2

IMPORTANT: WordPress 6.4 is compatible with exceptions with PHP 8.0, PHP 8.1, and PHP 8.2, and beta compatible with PHP 8.3.

What “compatible with exceptions” means?

• PHP 8.0
  • Named parameters. WordPress does not support named parameters.
  • Filesystem WP_Filesystem_FTPext and WP_Filesystem_SSH2 when connect fails.
• PHP 8.1
  • Not all “passing null to non-nullable” issues have been found.
  • htmlentities() et al needs the default value of the flags parameter explicitly set.
  • Replace most strip_tags() with wp_strip_tags().
• PHP 8.2
  • utf8_{encode|decode} deprecation with pending decision on requiring a PHP extension.
  • Unknown dynamic properties deprecations.
