Use data packs to control the sort of the creative inventory

Data packs should have section which allows for creative inventory sort file.

Each json will have a section for the items in the tab which contains item ids and/or item tags (which will add the items in order in the tag list), the tab icon item, the tab position (0-8), and an option for the page (which can be main to replace the main inventory or new to create a new page).

Example code which would replace the third 4th tab (transportation) with a stone pickaxe icon with 3 items in the first row, and 3 items in the second row.
{
    "icon": "minecraft:stone_pickaxe",
    "position": 3,
    "page": "main",
    "items": [
        {
            "minecraft:sand", "minecraft:stone", "minecraft:gravel"
        },
        {
            "minecraft:stone_axe", "#minecraft:foods", item:{id:"minecraft:potion",tag={Potion:"minecraft:slow_falling"}}
        }
    ]
}
