chore(DX-809): update to use preferred OIDC for npm publish in github actions

[lloyd-cio]

This PR converts the existing GitHub Action (GHA) workflow to use npmjs.com 's preferred authentication method (OIDC) to publish. "Classic tokens" that are currently configured (and dropped in this PR) will no longer work as of earlier this week.

I have manually tested this configuration works - published (then unpublished) a test version to the package managed by this repo.

Note - npmjs.com only allows a single GHA file to be configured to publish via OIDC configs, so I have dropped the manual publish step (and its script) in this repo. Please comment if this is a concern.

Note

Switches npm publish to OIDC in the deploy workflow, updating permissions and deploy steps to publish directly with npm.

• CI/CD:
  • Workflow /.github/workflows/deploy-sdk.yml:
    • Enable OIDC by adding permissions.id-token: write.
    • Update deploy-npm job:
      • Set environment: release and configure actions/setup-node with registry-url.
      • Install latest npm (for OIDC), then npm ci, run pre-deploy, and npm publish --tag latest.
      • Remove token/script-based publish (NPM_TOKEN, ./scripts/deploy-code.sh) in favor of direct publish.
