Fix tex and universal examples crash because of different React versions (#1756) (#1931)

Summary:
**Summary**

Fixes #1756, and #1930. The tex and universal examples have their own dependencies, and relied on a different version of `react`/`react-dom` from the one defined for Draft.js. This caused a JS error when running the examples.

I have also added the missing lockfile for the universal example.

**Test Plan**

- Make a clean copy of the project
- For both examples, go through the instructions to install their dependencies and build them.
- Open the examples in a browser, and attempt to type in the editor(s)
