Shiny Updates: Some plugins don't give visual feedback when clicking "Update"

[ericlewis]

e.g. Jetpack

We're performing some DOM traversal of the Plugins List Table based with a plugin's slug to orient ourselves, but the <tr>'s ID we're pivoting off is actually the plugin's Name with a sanitize_title() applied to it.

In 31831:

Ensure that we target the correct plugin row for update updates

The DOM traversal of the plugins list table was less than ideal. By switching to data attributes, we can better target the DOM elements we want to update.
