Update dokka to 1.9.10

[Jolanrensen]

All dokka dependencies are stuck on v1.8.10 until korro and docProcessor update their dokka versions to 1.9.10 as well.

After investigation:

df dokka 1.8.20 korro 0.1.6 - dokka 1.8.20 no doc preprocessor works

df dokka 1.8.20 korro 0.1.5 - dokka 1.8.10 no doc preprocessor works

df dokka 1.9.10 korro 0.1.6 - dokka 1.8.20 no doc preprocessor works

So I suspect korro is safe :) docProcessor is the culprit

Continuing:

df dokka 1.8.20 no korro doc preprocessor 0.3.2- dokka 1.8.10 works

df dokka 1.9.10 no korro doc preprocessor 0.3.2- dokka 1.8.10 works?

df dokka 1.8.20 korro 0.1.6 - dokka 1.8.20 doc preprocessor 0.3.2- dokka 1.8.10 works

df dokka 1.9.10 korro 0.1.6 - dokka 1.8.20 doc preprocessor 0.3.2- dokka 1.8.10 works?! huh?

I don't get it. It broke last time. Some gradle cache maybe?

Edit: I did these tests with clean assemble. I'll now retry with clean build as it looks like other stuff might break with that.

using clean build

df dokka 1.8.10 korro 0.1.5 - dokka 1.8.10 doc processor 0.3.2 - dokka 1.8.10 works

df dokka 1.8.10 korro 0.1.6 - dokka 1.8.20 doc processor 0.3.2 - dokka 1.8.10 breaks linter :(

df dokka 1.8.20 korro 0.1.5 - dokka 1.8.10 doc processor 0.3.2 - dokka 1.8.10 works

df dokka 1.9.10 korro 0.1.5 - dokka 1.8.10 doc processor 0.3.2 - dokka 1.8.10 works

df dokka 1.9.10 korro 0.1.6 - dokka 1.8.20 doc processor 0.3.2 - dokka 1.8.10 breaks linter
