Describe the bug
Player-planted kelp doesn't give any XP as it grows new sections.

Expected behavior
Should receive the Growth XP value of kelp when new sections grow.

To Reproduce
Steps to reproduce the behavior:

1. Plant kelp
2. Watch it grow
3. Feel the emptiness inside
4. See error

Versions:

• Minecraft: Seems to affect all versions (tested on 1.19.2 and 1.20.1)
• PMMO: Latest for each tested.

Additional context
My basil plant in my kitchen doesn't give farming XP either, but I can't find a repository to report that to.

So this is interesting. Sugar cane grows from the top block. Meaning if you can visualize the age of the block, you can see when it's going to grow next based on the top block. Kelp, however, always manages growth from the bottom. I suspect the issue with kelp not giving XP has to do with how i track growth which expects a bamboo or sugar cane style of growth.

I'm going to close this as not implemented. The change to make it work would be too invasive for such a unique use case.
