Revert "Replace brace with ace-build and react-ace (#1331)"

[Antonio-Maranhao]

Overview

Syntax check in the Code Editor is not working with the new react-ace component introduced in PR. The issue only happens in the release build. The editor works correctly with the dev server.

This PR reverts back to using brace by reverting commit 9fc82fb until the release build can be fixed for react-ace.
