Spikes Configured Feature to Allow Spikes of Any Material

Converting the Ice Spikes Configured Feature to a Spikes Configured Feature would allow developers to create spikes of any material.

I'm venturing into creating biomes via data packs, and noticed that some of the Configured Features (Ice Spikes) could easily allow me to create some more exciting features if they were able to be configured.

For a "configured feature", they sure don't have any configurations.
