This commit updates dependencies to latest.
It includes the latest wasm-tools, where support for resources has been stubbed
out with a `todo!`.
Hopefully that won't be too much of an annoyance for those actively developing
support for resources.
Additionally, `indexmap`, which is used extensively on many public APIs, has
been rev'd to a new major version; this resulted in no required source changes.
* Update Rust codegen for new WIT changes
* Update the markdown generation for new WIT

Enough has happened it seems reasonable to release everything now. There
have been a number of fixes to Rust and other generators and
additionally there's a new Go generator!
