Add plugin packages to the release registry

[Lms24]

We should think about adding the plugin packages to the release registry. The webpack plugin was never added but it def doesn't hurt to do it. Perhaps it might even be helpful in the future.

Open question:

• Can we say that the plugins are sdk packages?

This is low-prio. Just adding this issue so we don't forget it

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
