I think it should be fine to use snowflake 2.0.0 with Liquibase 3.8.0. We don't make API-level changes without updating the minor version number, so all the 3.8.x versions should be compatible.
I do know taht the snowflake extension is fairly new and limited in scope, so I am going to guess that the extension just doesn't have support for all the things that are needed for the dbDoc command to work. Will probably need to file an issue or a pull request with the snowflake extension at https://github.com/bruce-szalwinski/liquibase-snowflake
