[MC-238540] Ruined portals generate floating in rivers instead of underwater

Ruined portals generate floating on water in any biome that is not an ocean instead of being submerged. I could not find a great example of this in 21w40a, but they can generate without even touching any solid blocks in wide rivers.

Examples:

386 68 -22726

381 65 -31362

Ruined Portals
Shattered remains of ancient nether portals. Wonder who built them?
They can be found in any overworld or nether biome
Some are hidden underground, under the sea, or buried in sand

Just to clarify many portals still generate underwater in ocean biomes, but the floating ones are all in rivers, beaches, or land biomes that extend into the ocean when they shouldn't.
