Rollup merge of rust-lang#68620 - kubkon:patch-1, r=Dylan-DPC

Update links to WASI docs in time.rs module

Since the docs for the WASI API are now evolving in [WebAssembly/WASI] repo,
I thought it might be useful to update the links in the docs to point to that location
instead of using the outdated `CraneStation/wasmtime` destination.

[WebAssembly/WASI]: https://github.com/WebAssembly/WASI
