impl: support for GW 2023

- there were a couple of API incompatibilities especially around remote path validation
  which now expects a more complex parameter. Fortunately there is an already existing
  helper hiding all that, that is also compatible with 2022.3
- some deprecated horizontal alignment parameters are now removed in GW 2023. Replaced them
  with the recommendations.
