[Updates] Problems with Relearn v7.0.0 and Hugo v0.136 (and later)

[cagix]

With the update to Relearn v7.0.0 our customised archetypes no longer work. A first simple attempt to replace the ‘archetype’ with ‘type’ was not successful. Following information in McShelby/hugo-theme-relearn#927, I also moved the old archetypes to the new locations - unfortunately without success. An update to v7.0.x is therefore out of the question for the time being - which also blocks new Hugo versions.

With Hugo v0.136 one of the deprecation warnings becomes an error - i.e. Hugo v0.135 is the last working version.

For a short period of time, we can work with Relearn v6.4.1 and Hugo v0.135 (last working versions). A security problem could arise here at some point. A switch to another platform (Docsify, LiaScript) seems appropriate and more urgent. (This would also significantly streamline our workflow).
