This is due to

skimage (0.21.0-2) unstable; urgency=medium

  * Drop Don-t-import-unavailable-imageio.v3.patch: package is available now

Updating the build dependency to python3-imageio (>= 2.31.1-1)
(which will also version the runtime dependency) will ensure
that a recent enough version of python3-imageio is installed
when building or running skimage.
