[Fabric 1.20.1] Mythic Metals breaks merling origin swim speed due to shipping newer Additional Entity Attributes

[Mouy07]

Summary
When using the latest version of Mythic Metals (0.19.8) with Origins, the merling origin's increased swim speed does not work. Issue is not present in earlier versions.

Version Details
Minecraft 1.20.1
Fabric 0.15.11
Mythic Metals 0.19.8
Origins 1.10.0

Expected Behavior
When using merling origin, underwater movement speed will be increased to 4.9 m/s while walking and 9.8 m/s while sprinting.

Observed Behavior
Merling underwater movement speed is unchanged from default (1.96 m/s walking, 3.92 m/s sprinting).

This is not directly caused by Mythic Metals. It is caused by the bundled version of Additional Entity Attributes. Currently I ship 1.7.4, while Origins is still built against 1.3.0.
I don't think there is a ton I could do to fix this, as the best fix would be for Origins themselves to update that dependency.

Ah that makes sense. Thanks!
