The Deepslate Redstone Ore isn't in the `Redstone Blocks` tab

What I expected to happen was...:
The Deepslate Redstone Ore should be put into `Redstone Blocks` tab, for the Redstone Ore was put in this tab.

Steps to Reproduce:
1. Run Minecraft and switch your gamemode to Creative Mode.
2. Open `Redstone Blocks` tab.
3. You'll see that `Deepslate Redstone Ore` IS NOT in this tab.
