Add funding metadata to publishable package manifests

[Copilot]

This updates the publishable packages to include funding metadata in their distributed package.json files, and ensures the expected package-level references remain present for publish output.

• Publish manifest metadata

  • Added funding to:
    • ts-plugin/package.json (@nevware21/grunt-ts-plugin)
    • eslint-ts-plugin/package.json (@nevware21/grunt-eslint-ts)
  • Funding points to the existing GitHub Sponsors profile for the project.

• Scope alignment with publish targets

  • Limited changes to the two Rush projects marked as publishable.
  • Left non-published package manifests unchanged.
