Upgrade/Install: Prevent users from sending multiple bulk plugin updates.

This changeset improves `update.js` by adding `is-enqueued` class to enqueued plugin updates to prevent users from asking for several updates for the same 
plugin at the same time, which previously resulted to …an interesting experience.

Fixes #40966.
