fix: use rules_rust fork with _symlink_sysroot_tree fix

Override rules_rust 0.68.1 with fork that fixes the bug where
target_files parameter was ignored in _symlink_sysroot_tree.
This ensures wasm-component-ld is symlinked into the sysroot,
fixing Windows builds for wasm32-wasip2 targets.

See: bazelbuild/rules_rust#3727
