Is it fine to push new versions to crates.io if they don't contain new updates?

I recently did a full overhaul of my documentation for a crate I wrote. I was wondering if it's fine to push a new version to crates.io, or if it should be avoided. Also, is there any way to update my docs on docs.rs without publishing to crates?

I just notice whenever I push a new version I get a ton more downloads and it feels manipulative to push a new version when all I've changed is docs.
