remoteEntry.mjs not optimized

[gultyayev]

Current Behavior

When you build non-dev builds – remoteEntry.mjs is not minified. Thus, it's ~2x the size it could've been otherwise.

Expected Behavior

It should be minified even if it has .mjs which it has by default.

Steps to Reproduce

1. Clone repo
2. npm install
3. nx run-many -t build
4. Check the dist/apps/about/remoteEntry.mjs and see that it's not optimized

Additional Information

If I modify the entry file name (by typecasting to any as it's a hidden interface option) to have .js extension – it is minified. So, it seems to be not picked up by the optimizers due to its extension only.
