Update Docusaurus once again

This commit changes the following things inside the logging infrastructure:
- passing issuerClass, issuerOrigin and issuerMetadata is no longer required, relevant information is now being pulled from the stack
- split huge classes into multiple smaller ones
- separated "normal" and asynchronous logging classes
- simplified logging
- improved performance
- more detailed crash reporting
- regex-based filtering
- internal placeholders have been replaced with more lightweight method calls
- much more changes
