System Information
Operating system: Linux-5.17.15-76051715-generic-x86_64-with-glibc2.35 64 Bits, X11 UI
Graphics card: Quadro RTX 6000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 515.48.07

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, commit date: 2023-04-20 10:26, hash: 475f9a3e23fc
Worked: Before e45ed69349

Short description of error
Before (actual rest position):

After (outdated rest position attribute):

When a rest_position attribute exists on the mesh, the Add Rest Position functionality does not overwrite that existing attribute and ends up not doing anything.
This behavior was changed implicitly with e45ed69349

Exact steps for others to reproduce the error

geonodes_rest_position.blend

from scratch:

enable add rest position
add a rest_position attribute (for example by running Convert to mesh )
