fix: revert wit_deps_check to use run_shell for output redirection

Fix analysis failure in wit_deps_check rule caused by using unsupported
stdout parameter in ctx.actions.run(). The stdout parameter is not
supported in ctx.actions.run(), so revert to using ctx.actions.run_shell()
for output redirection.

This resolves build failures in:
- //test/integration:validate_consumer_deps
- //test_wit_deps/consumer:check_deps

The run_shell approach is appropriate here since it's a simple tool
invocation with output redirection, which is a legitimate shell use case.
