Allow right-click actions on Draconic Reactor Core

[Luminyx1]

In 1.12.2, active/supercritical draconic reactor cores can't be focused by the player which can be seen in 3 ways:

• HWYLA doesn't tell you about it when looking at it
• Time in a Bottle can't be used to speed up the explosion
• Mekanism cardboard boxes can't be used to transport the core

The tweak I am requesting would fix this since all 3 are working in 1.16 DE, and I would like this functionality to be backported to 1.12.2 because it's fun. Thanks!
