Update WRS to 0.8.0 and async_channel to 2.0.0

[aspect]

This PR updates workflow-rs to 0.8.0 to enable accept() functionality in wRPC needed for the file descriptor budget pool being implemented in #284

As workflow-rs updates the async_channel dependency to 2.0.0, it is also updated.

Why do some of the references in this lock refer to 1.9.0 and why some 2.0.0?

[aspect]

async_std still uses an old version of async_channel and is thus a dependency of the project, however we make it a point that we use async_channel everywhere directly (I actually went over the code and corrected this where it was not so).

[aspect]

Just to add: we can’t use same crates with different versions in any code that builds to WASM as wasm-pack will error out with naming collisions. To make sure this doesn’t occur by an accident, we have /test script build WASM after running tests. (and CI itself builds WASM as a separate stage). So the noted dependency is benign.

[aspect]

Closing as same changes are coming in with #303 and #305.
