chore: update release scripts for the TypeScript CLI (#1472)

This introduces two changes to make a quick fix so we can deploy the
Rust CLI for `0.2.0` of `@openai/codex` on npm:

- Updates `WORKFLOW_URL` to point to
https://github.com/openai/codex/actions/runs/15981617627, which is the
GitHub workflow run used to create the binaries for the `0.2.0` release
we published to Homebrew.
- Adds a `--version` option to `stage_release.sh` to specify what the
`version` field in the `package.json` will be.

Locally, I ran the following:

```
./codex-cli/scripts/stage_release.sh --native --version 0.2.0
```

Previously, we only used the `--native` flag to publish to the `native`
tag of `@openai/codex` (e.g., `npm publish --tag native`), but we should
just publish this as the default tag for `0.2.0` to be consistent with
what is in Homebrew.

We can still publish one "final" version of the TypeScript CLI as 0.1.x
later.

Under the hood, this release will still contain `dist/cli.js`,
`bin/codex-linux-sandbox-x64`, and `bin/codex-x86_64-apple-darwin`,
which are not strictly necessary, but we'll fix that in `0.3.0`.
