docs: remove divs from all notes/warnings (#1572)
This branch removes the HTML `<div>` tags from the warning and note blocks in the documentation, because they're screwing up RustDoc rendering on docs.rs. We had done this previously on the `master` branch, but apparently it never made it to `v0.1.x`. This should fix #1571 once a new `tracing` version is published.
