You don't actually need two cameras, it works fine with a single one targeting both eyes for me. Lighting looks wrong though, no matter whether you use two cameras or one. The reflections of a light source are way too far apart on each eye:

Hi there,
Could reproduce the issue with fluid not rendering on separate cameras in 2020.3 and above. Not sure what has changed in Unity's side for this to stop working, going to investigate and get back to you.
All fluid lighting us calculated using the eye-space position of the fluid. Since the fluid's surface is not a mesh but an implicit function, positions are reconstructed from the depth buffer and the camera's frustum data (which is passed to the fluid shaders from the CPU). For this reason, fluid rendering can't possibly work using single-pass stereo or multipass, since the frustum data passed to the shader will be wrong and so will be all lighting calculations. You do need two cameras for it to work correctly.
I couldn't reproduce the lighting issues you describe when using two cameras, though. I'm on Unity 2019.4.30f1, using Oculus Quest.
