fix webpack 5 polyfills

[k2s]

When using cgm-remote-monitor as part of monorepo I got errors because incorrect module resolution. The problem is explained here https://gist.github.com/ef4/d2cf5672a93cf241fd47c020b9b3066a.

I tested that it has no impact on size of the result, it only provides more proper way to resolve the process/browser and events modules.
