Describe the bug
Blocks skipped by Jackhammer are:

• Air,
• Liquids,
• c:ores,
• Obsidian and Crying Obsidian
• Ancient Debris
• Redstone Ore

Can be fixed by creating a tag that contains all the blocks that Jackhammer skips, and checking whether the block is tagged as such.

• Minecraft: Any (though 1.19.3 brought an improvement replacing the instanceof check for OreBlocks with a c:ores tag check)
• Mod Loader: Fabric

Logs
None

Additional context
Add any other context about the problem here.

The tag is there for a reason - adding #minecraft:sand to #c:sand when there are two separate tags would be pointless, with #c:sand not including Suspicious Sand on purpose.

EDIT: After glancing onto the Fabric repository, c:sand is not a default convention tag.

Alternative idea: A "negative" tag, containing blocks skipped by Jackhammer, evaluated before the mineable tag.

Cool, although here's a thing:
Sands and Sandstones should totally have c or minecraft tags.
(To make it compatible out-of-the-box with other mods that add Sands/Sandstones, such as Ad Astra).

#minecraft:sand contains suspicious sand also. Which shouldn't be broken by Jackhammer, IMHO.

Though breaking of Suspicious Sand with the Jackhammer can be fine (it's a block which you need to be careful to not destroy it by accident)

And Jackhammer skipping it kinda kills the "carefulness" part.

TR is not usually played alone, together with vanilla Minecraft only, it's usually played in big packs.

Sand tags:

Suspicious Sand Tags:

Aka c:sand can be used there.

This will perfectly work until somebody will decide to add #minecraft:sand to #c:sand.
Modpack author can add some modded sand to #techreborn:jackhammer_mineable
