refactor: migrate to new jsx runtime

[Daniel-Mendes]

Summary

I followed the official instructions from the react blog: https://legacy.reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html

I tried keeping the minimum changes, but the codemod impacts a lot of files.

Test plan

I build the project and run the test:ci locally.
