I tried updating react-scripts to v 5.0.1, but that broke the build at step Build React App with "Can't resolve 'stream'".

Specific Changes

Override "es5-ext" downgrading it to "0.10.53". (0.10.60 is the latest version.)

This fix resolves the es5-ext 0.10.60 critical alert and stops the build from failing.

Add Component Governance task. This replaces the injected CG task, which only runs against the main branch. It makes testing CG fixes easier.
