Guidebook reagents could do with some reorganisation.

Description

The main offender is the "Others" category, many of the reagents listed there fit into existing categories or could be moved to more informative new categories. i.e Some elements are there instead of in "Elements", gases could be added to a new gases category, pretty sure there are quite a few other reagents that could be moved, but not looked extensively yet.

Reproduction
Look at the "Others" category for reagents in the guidebook. It is very large and doesn't have any recognizable order to it.

Additional context
I think "Others" might be the largest sub-category list right now, which seems a bit off. Also the formatting in the game files and for the guidebook summary doesn't match the general convention.

Yep, same for the files they are in. The yaml files for the reactions mirror the files for the reagents, but they are not consistently sorted into their categories.

I've been looking at reactions and happened to stumble upon issue #27543. I was hoping I could just do some simple .yml editing to get this working, but it is starting to look a bit more complicated than that. I'm probably going to start working on a PR to address the issue posted here, but with a bit of luck I might be able to incorporate the reactions category suggested in that related issue.

Nearly finished a PR for this. Just holding off to go over the files and do any reformating/rearanging internally, while they are being edited anyway.
