clean up dev-dependencies

[tool.poetry.dev-dependencies]

IMHO not all of the packages listed here are actually necessary and should therefore be removed, especially because some of them have again quite many other packages as dependencies

I'd suggest to remove everything which is not needed for usual development stuff like testrunnsers, linters, formatters

kick out:
django-extensions = "^3.0.9"
networkx = "^2.5"
jupyter = "^1.0.0"
spacy = "^2.3.2"

don't know what those are used for:
lastversion = "^2.0.1"
xlrd = "^1.2.0"
openpyxl = "^3.0.5"
yapf = "^0.30.0" (alternative to flake8?)

why?

• this would avoid PRs like Bump nbconvert from 6.5.0 to 6.5.1 #350
• avoids installing actually superfluous and potentially outdated packages
