Remove dev deps for building tari.js

[MCozhusheck]

  "dependencies": {
    "@tariproject/tarijs": "https://gitpkg.now.sh/tari-project/tari.js?main&scripts.postinstall=npm%20run%20build-tsc",
  },
  "devDependencies": {
    "@rollup/plugin-node-resolve": "^15.2.3",
    "rollup-plugin-typescript2": "^0.34.1",
    "@types/node": "^20.12.6"
  }

These 3 dependencies are only required by npm run build-tsc during installation of @tariproject/tarijs from main branch.
After there is gh action for automatic release these dependencies will be redundant and should be removed
