Turtles now rotate their front fins along the x axis while swimming

In snapshots leading up to the release of 1.21.2 (24w35a to be exact), Turtle swimming animations were randomly changed so that their front fins will also rotate along the x axis. This is possibly a bug, as it was not mentioned in any other snapshot changelogs leading up to 1.21.2 or the actual 24w35a changelog itself.

 

Step to Reproduce:
1. Spawn a Turtle in the water on 1.21.1 or an older version
2. Spawn a Turtle in the water on 1.21.2 or a newer version
3. Look at the Turtle's front fins while it is swimming in both versions, they will rotate along the x axis after 1.21.2 despite this change not being listed in any changelogs

Expected Result:
Turtles only rotate their front fins along the z axis while swimming like they did in previous versions OR this change is acknowledged as intentional

Observed Result:
Turtles will now rotate their front fins along the x axis while swimming
