WebAssembly: add WASIP1 runtime configuration examples
This change adds a "WASIP1 Runtime Configuration" section to the
WebAssembly page.
It provides configuration examples for Wasmtime, Wazero, and Node.js
to properly map the host directory to the guest root `/` and set `PWD`.
Without this configuration, Go programs compiled for `wasip1` often
fail with "Bad file number" errors instead of the expected
`fs.ErrNotExist` when accessing non-existent files or calling
`os.Getwd()`.
For golang/go#60732
