POC: Fixed fonts and images loading

[Vorbert-Kruk]

Description

Some time ago we've had css-loader in version 3rd, recently it was updated to version 6th, which resulted in having issues with fetching fonts and images. After doing an investigation it appears that version 6th of css-loader have started giving us issues (5h and 4th were working just fine) Due to that I've went through their migration guideline and applied necessary fixes not only to mechanism of exposing fonts, but also for images.

Overall, the fixes are:

• Removing "." in url, as [ext] variable comes with it out of the box
• Adjusting structure to be basing on native webpack 5 functionalities, as suggested by community
