Add ts-node dep - needed to read jest.config.ts

[hsubox76]

e2e tests are failing because

$ yarn jest tests/modular.test.ts
$ /home/runner/work/firebase-js-sdk/firebase-js-sdk/e2e/node_modules/.bin/jest tests/modular.test.ts
Error: Jest: Failed to parse the TypeScript config file /home/runner/work/firebase-js-sdk/firebase-js-sdk/e2e/jest.config.ts
  Error: Jest: 'ts-node' is required for the TypeScript configuration files. Make sure it is installed
Error: Cannot find package 'ts-node' imported from /home/runner/work/firebase-js-sdk/firebase-js-sdk/e2e/node_modules/jest-config/build/readConfigFileAndSetRootDir.js

So I added ts-node. Hopefully this works.
