Merge 53f598192c into 3b162996ad

The GitHub action is changed:
- Newer version of Checkout Action
- Caching of PlatformIO files
- All build firmwares (.bin / .hex) are bundles into a files
- All firmwares runnable on Wokwi are run as simulation

n.b.: To run on Wokwi a secret credetial has to be stored on the account.
