[MC-189561] Ocean ruin spawned under seafloor

An Ocean Ruin spawned under the seafloor, making it completely hidden

What I expected to happen was....

Either the ruin to spawn above the seafloor or not at all

What actually happened was....

The ruin spawned under the seafloor, making it unreachable

Steps to reproduce:

Create a world with the seed 1451222223
Go to 184, 30, 68 in Spectator Mode
```
/tp 184 30 68
```

Find the Ocean Ruin spawned under the sand with the Chest overwriting the block that was there and most adult Drowns suffocated in a block

I am unable to reproduce in 1.17-pre4.

I was able to reproduce this bug in Minecraft 1.18, so it likely happens in 1.19 as well on the seed 1451222223 at the coordinates 184, 30, 68. The ocean ruin generates in a really weird spot, and there are three chests that are completely hidden.

Can confirm in 1.21.3 using the seed/coords listed below. The seed in the report is outdated. Also would like to request ownership of this report to maintain it/update the description.
