feat(example): add logging and keyvalue for tutorial use

[brooksmtownsend]

Feature or Problem

This PR adds wasi:keyvalue and wasi:logging to the wit dependencies for both of our hello world examples for use in the quickstart tutorials. Without this, developers would need to manually modify the deps.toml file and run wit-deps update, so now during the quickstart documentation they can simply add these imports to their wit/hello.wit file and then use the capabilities.

This is only a temporary fix. Ideally these examples don't come with a wit deps directory at all and the only wit modification needed will be to specify custom import/exports, and a crate like wasmcloud-actor would be used to wrap wit definitions. I think that it's important to start here as a baseline and then remove some of the low level WebAssembly concepts as we can, as this level of detail will be necessary for languages where we don't have some sort of higher level SDK or library support.
