Using runner tag 'poetry-56' replacing test-3.5 job load

aiohttp updated to v3.7.1
multidict updated to v5.0 which drops Py 3.5 support

Requires Python 3.6.8
Remove test job

Not added as a direct dependency, since it is a DuniterPy dependency
And Silkaj won't get away from DuniterPy, nor DuniterPy will stop using
base58.

Not compatible with Poetry v1.0
Update dependencies

- Set poetry-core v1.0.0 as requirement and new build system
https://python-poetry.org/blog/announcing-poetry-1-1-0.html
