Narrow return and parameter type of several wp_robots_*() functions

[IanDelMar]

Types narrowed for

• wp_robots_max_image_preview_large
• wp_robots_no_robots
• wp_robots_noindex
• wp_robots_noindex_embeds
• wp_robots_noindex_search
• wp_robots_sensitive_page

All of these accept and return an

Associative array of directives. Every key must be the name of the directive, and the corresponding value must either be a string to provide as value for the directive or a boolean true if it is a boolean directive, i.e. without a value.

Source: wp_robots()

true has been relaxed to bool as it makes no difference as long as wp_robots() does this loose comparison:

if ( is_string( $value ) ) {
    // ...
} elseif ( $value ) {
    // ...
}
