Import error when using python 3.11

[strayMat]

Hello !
I have an import error when using metanno with python 3.11. It seems to be linked to the collection package :

It might be relevant either :

• to modify the typing to be supported by python 3.11: For this, using collections.abc.Sequence instead of collections.Sequence might do the trick. I can try to provide a PR.

• to change the pyproject.toml to explicitly not support python 3.11

Hi @strayMat, indeed metanno is currently compatible only with python 3.9, for typing issues but also because of the python -> js transpilation step. The next version should relax these requirements, but I don't have a timeline for its release at the moment
