fastchan is missing platformdirs 3.10.0

[sethfri]

I tried to run mamba install -c fastchan fastai but it fails, hitting a 404 error in trying to download platformdirs version 3.10.0 (error below). Looking at Anaconda, it looks like the latest platformdirs version in fastchan is indeed 3.9.1 instead of 3.10.0, but it is 3.11.0 in conda-forge.

Multi-download failed. Reason: Transfer finalized, status: 404 [https://conda.anaconda.org/fastchan/noarch/platformdirs-3.10.0-pyhd8ed1ab_0.conda] 17 bytes
