Filters whether to automatically update core, a plugin, a theme, or a language.

The dynamic portion of the hook name, $type, refers to the type of update
being checked.

Possible hook names include:

• auto_update_core
• auto_update_plugin
• auto_update_theme
• auto_update_translation

Since WordPress 3.7, minor and development versions of core, and translations have
been auto-updated by default. New installs on WordPress 5.6 or higher will also
auto-update major versions by default. Starting in 5.6, older sites can opt-in to
major version auto-updates, and auto-updates for plugins and themes.

See the {@see ‘allow_dev_auto_core_updates’}, {@see ‘allow_minor_auto_core_updates’},
and {@see ‘allow_major_auto_core_updates’} filters for a more straightforward way to
adjust core updates.

$update = apply_filters( "auto_update_{$type}", $update, $item );
