Complete missing docstrings in keras-core/ops/core.py

[Frightera]

Most of the py files have the functions defined in that module at top:

Example:

"""
scatter
scatter_update
slice
slice_update
while_loop
stop_gradient
shape
cast
convert_to_tensor
convert_to_numpy
"""

Should they be removed?

Also if there's a single example, use Example: as the section title
