Update Dask to the version 2022.11.1

The update of Dask to version 2022.11.1, currently the latest upstream version, fixes an incompatibility issue with recent xarray versions, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1022338 and https://github.com/pytroll/satpy/issues/2248.

The upgrade seems to be blocking both for xarray and satpy RC bugs.

Please note that this PR is still incomplete:

• there are 2 new build dependencies, for documentation, that are still not packages (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1013092, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1017487). Not sure if it is possible7makes sense to create a patch to build without them
• a new cli tool called dask is not installed, it would need a man page and a dedicated package or a lintian-override

IMPORTANT: to have this MP properly working all the debian/main, upstream and pristine-tar should be merged.
