chore: demote missing_docs lint to warn

`#![deny(missing_docs)]` makes `cargo test` abort immediately
if any public API member is missing a doc comment ...
which is quite annoying when experimenting with API designs.

Also sometimes refactor commits (such as the very next commit)
introduce new types that are then immediately removed afterwards,
this should be possible without having to add a `/// TODO```
(which contrary to a compiler warning is easy to miss).
