Add "Select all" option to Integration Updates page

As a user, I want the ability to "select all" updates on the Integration Updates page, so that I do not have to select each change to send manually.

When the user has set up integrations on a workspace, if there are issues with some of the integrations that are meant to be sent automatically, they are shown on the "Integration updates" page. On this page, you have to select each item one by one in order to send the updates.

This is inefficient. We should be able to select all at once, or have the default behavior be that if none are selected, then all are sent (or ignored if the user selects that option).
