Fix plugin/theme delete/install success hook inconsistency

[olarmarius]

The delete hook name for plugin deletion is "wp-plugin-delete-success" and for theme "wp-delete-theme-success". We need to resolve this inconsistency.

A) wp-delete-plugin-success & wp-delete-theme-success
B) wp-plugin-delete-success & wp-theme-delete-success

As pointed out by @olarmarius, the install actions are also inconsistent.

Updates: Standardize JS Custom Event Names

Custom JS events are triggered on the document in order for plugins to have something to hook into. The standard began in #31819 is dash separated and begins with wp to signify the namespace, followed by the subject of our action ( "theme", "plugin", etc.) followed by the action and an optional indicator of status ( "install-success", "deleting" ).

This brings some of the theme hooks in line with the standard. As of now, all plugin actions in src/wp-admin/js/updates.js have an equal corresponding theme action.

Fixes #37598.
See #37512, #37216, #31819.
