Fix ktlint issues

Turns out experimental:function-signature is a feature of ktlint 0.46.+
which is something we can not use yet since the gradle plugin we're
using does not support it yet, relevant issue here:
JLLeitschuh/ktlint-gradle#589

This also required to downgrade to the gradle plugin ktlint version
0.9.1 from 0.10.0 so that the IDE hints do not show different rules as
well.
