wp_remove_object_terms() should pass $taxonomy to its actions

[boonebgorges]

wp_set_object_terms() passes the $taxonomy parameter to its actions, but wp_remove_object_terms() does not. This makes it hard to target term removal for specific taxonomies.

[Takahashi_Fumiki]

Add 3rd param to 'deleted_term_relationships' action.

@boonebgorges function wp_remove_object_terms() doesn't seem to have set_object_terms actions equivalent.
So, I add a new param to deleted_term_relationships action but it is equivalent of added_term_relationship.

[Takahashi_Fumiki]

Add 3rd param $taxonomuy to 'deleted_term_relationships', 'delete_term_relationships', 'added_term_relationship', 'add_term_relationship' actions.

[Takahashi_Fumiki]

wp_remove_object_terms() function doesn't have the equivalent of set_object_terms action.
Add new argument $taxonomy to all of actions below:

• add_term_relationship
• added_term_relationship
• delete_term_relationships
• deleted_term_relationships

They don't equals completely (singular/plural), but they are similar.

This looks great, @Takahashi_Fumiki. Thanks for the patch!

One more small request: Could you please add @since annotations for the new parameters? Something like:

 * @since 4.7.0 Added the `$taxonomy` parameter.

See ​https://make.wordpress.org/core/handbook/best-practices/inline-documentation-standards/php/#since-section-changelogs for more information.

Add since tag to inline document.

@boonebgorges Thank you for your adivice. Added @since tag.
