Bump async-task (#13062)

Bumps `async-task` to 4.7.0 , note this is what Cargo.lock has as well.
Building as a dependency gives the following:

```
   Compiling async-channel v1.8.0
   Compiling futures-lite v1.12.0
error[E0432]: unresolved import `async_task::Builder`
  --> /Users/daniel/.cargo/registry/src/index.crates.io-6f17d22bba15001f/async-executor-1.8.0/src/lib.rs:46:18
   |
46 | use async_task::{Builder, Runnable};
   |                  ^^^^^^^ no `Builder` in the root
   |
   = help: consider importing this struct instead:
           std::thread::Builder

For more information about this error, try `rustc --explain E0432`.
error: could not compile `async-executor` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...
```

With this change, builds correctly
