chore: use NPM trusted publishing (#3071)

Replaces the ADO-based npm publish pipeline with a GitHub Actions
workflow that uses npm Trusted Publishing (OIDC) for the main publish
step — no stored npm token required for `npm publish`.

## Changes

- **`.github/workflows/microsoft-npm-publish.yml`** — New workflow
triggered on `*-stable` branch pushes. Runs in an `npm-publish` GitHub
environment (add protection rules there). Uses `id-token: write` +
`--provenance` so yarn exchanges a GitHub OIDC token directly with
npmjs.com rather than a stored secret. The `npm dist-tag add` step
(applying additional dist-tags) still requires a `NPM_TOKEN` secret
since OIDC doesn't cover that operation.

- **`.ado/scripts/configure-publish.mts`** — Added
`enablePublishingOnGitHubActions()` that writes
`publish_react_native_macos=1` to `GITHUB_OUTPUT`, so the new workflow
can gate its publish steps on this output. Previously only the ADO
`##vso[task.setvariable...]` signal was emitted.

- **`.ado/scripts/apply-additional-tags.mjs`** — Token can now come from
`NODE_AUTH_TOKEN` env var as a fallback to `--token`. When using the
env-var path (GHA), the token is not passed as a CLI argument —
`actions/setup-node` has already wired `NODE_AUTH_TOKEN` into `.npmrc`,
so `npm dist-tag add` picks it up from there. The `--token` CLI arg path
(ADO) is unchanged.

## Manual steps required before this workflow runs

1. **npmjs.com**: add a Trusted Publisher for `react-native-macos` and
`@react-native-macos/virtualized-lists` — repo
`microsoft/react-native-macos`, workflow `microsoft-npm-publish.yml`,
environment `npm-publish`
2. **GitHub repo Settings → Environments**: create the `npm-publish`
environment with desired approval rules
3. **GitHub secret**: add `NPM_TOKEN` to that environment (granular
automation token scoped to the two packages, used only for dist-tag
operations)
4. **ADO**: once verified, disable `.ado/publish.yml`
