Icicles and sulfur spikes are not part of the `#dangerous_for_teleportation` block tag, unlike pointed dripstone

The Bug:

Icicles and sulfur spikes are not part of the dangerous_for_teleportation block tag, unlike pointed dripstone.

Steps to Reproduce:

1. Open the 26.4 Snapshot 4 jar file and locate the data/minecraft/tags/block/dangerous_for_teleportation.json file.

2. Observe if icicles and sulfur spikes are listed beside pointed dripstone.

Observed Behavior:

The block tag dangerous_for_teleportation lists pointed dripstone but not icicles or sulfur spikes.

Expected Behavior:

The tag would list icicles and sulfur spikes too, as the pathfinding tags already do through speleothems.
