Improve preparation of app bundle, revise dependencies

[grzanka]

We have several issues with deployment process:

• JS bundle produced with web pack is pretty large (~20 MB) now which leads to very long app loading time (~15 sec)
• process of creating the bundle is quite long (few minutes)

There are several ongoing issues to address that:

• Speed up build time #681
• Examples should be loaded from public instead packaged into app JS bundle #1598

This probably won't solve the problem completely. From my studies on #1598 (comment) it seems that the heaviest component in the bundle is related to babel. @ostatni5 mentioned in the PM that babel should be moved from production deps to development dep.

Here I would like to discuss how to revise the dependencies in the project. Maybe first we should sort out what is needed and what is not. Maybe that itself should solve of the issue and make easier the transition to other building platform (like vite)

@NiEkOKsU please write down in a comment a review of the deps added in PR related to vite

If dependencies cannot be reduced another solution would be to split the bundle into smaller chunks for views/features and load them dynamically.
