Introduce a pnpm dependency check in the CI

[mkleszcz]

Description

Often during development there will be unused or old node_modules dependencies which can be easily forgotten to remove or change. It would be good to have an automatic check that will point out dependencies that are not needed anymore.

Describe the solution you'd like

There are some tools available like: https://github.com/depcheck/depcheck
We need to do a research about other tools, find the best and implement it.
