VILLASnode Examples do not run in current Dev container

[JTS22]

When using the dev-container from the current Dockerfile.dev, none of the VILLASnode-Examples can be executed, because they require the presence of the libxil shared library (https://github.com/VILLASframework/libxil). Because the last push of the dev image to Docker hub happened over 6 months ago, the pipeline still uses an outdated image, in which this dependency was apparently not present. Therefore, the VILLASnode-Examples still work in the GitHub-Pipeline, but not locally.
Options to resolve this are:

1. Compile VILLASnode with the WITH_FPGA=OFF option to disable the dependency (as in Disable VILLASfpga to remove libxil dependency #232 )
2. Somehow install the dependency manually in the dpsim-Dockerfile
3. Update the VILLASnode version used in the DPsim-containers (see Update VILLASnode version #233), as the issue has been fixed there (update fpga submodule VILLASframework/node#694)

We target to implement the third option.

The VILLASnode version and, correspondingly, the Docker hub dev image have been updated with the merge of PR #245
