Is your feature request related to a problem? Please describe.
Two sources of fire do not provide any heat to Crucibles. The Shroomlight, which was added after Campfires, does provide heat - this makes me think that Campfires were missed accidentally.

Describe the solution you'd like
Campfires and Soul Campfires should provide the same amount of heat as normal/soul fires do. Because that's literally what they are.

Describe alternatives you've considered
N/A

Additional context
Tested on latest 1.16.5 versions with just JEI and Ex Nihilo Sequentia.

that's true. we might add it to next 1.16.5 release. as a workaround, you can make a datapack and add it yourself.
