fix(cli): set napi object property properly (#26344)

<!--
Before submitting a PR, please read
https://docs.deno.com/runtime/manual/references/contributing

1. Give the PR a descriptive title.

  Examples of good title:
    - fix(std/http): Fix race condition in server
    - docs(console): Update docstrings
    - feat(doc): Handle nested reexports

  Examples of bad title:
    - fix #7123
    - update docs
    - fix bugs

2. Ensure there is a related issue and it is referenced in the PR text.
3. Ensure there are tests that cover the changes.
4. Ensure `cargo test` passes.
5. Ensure `./tools/format.js` passes without changing files.
6. Ensure `./tools/lint.js` passes.
7. Open as a draft PR if your work is still in progress. The CI won't
run
   all steps, but you can add '[ci]' to a commit message to force it to.
8. If you would like to run the benchmarks on the CI, add the 'ci-bench'
label.
