Make nessie-demos usable (again)

Currently all Nessie Demos are unusable. This change makes those usable again, and updates a bunch of dependencies. The changes in detail are:

* Bump Python from 3.7 to 3.10. Python 3.11 does not work, because of some issues with not-well maintained dependencies - Flink (a version that's supported by Iceberg), pandas + numpy.
* Bump Nessie from 0.30.0 0.74.0. This required to have both Java 8 and Java 11: Hive requires Java 8, Nessie at least Java 11, Spark Java 11. Add safety checks to validate that both Java 8 and Java 11 are configured.
* Bump pynessie from 0.30.0 to 0.65.0.
* Bump Flink from 1.13.6 to 1.17.1
* Bump Hadoop from 2.10.1 to 2.10.2
* Bump Iceberg from 0.13.1 to 1.4.2
* Bump a bunch of dependencies in `requirements_dev.txt` + `requirements_lint.txt`
* Bump dependencies in `pre-commit-config.yaml`
* Remove Delta-Demo due to dropped support for Delta Lake.
* GH Actions
  * Introduce `concurrency` group
  * Cache downloaded tools (Hadoop, Hive, Spark)
  * Add a check that the `FROM` statement in `Dockerfile` starts with the right prefix. The `build_run_local_docker.sh` script temporarily updates the `Dockerfile` by updating the `FROM` statement to make it work locally. Committing the temporary change is wrong.
* Made startup of Nessie safer by adding a check whether the required port 19120 is listening.
* Made startup of Hive-server safer by:
  * Adding a check whether the required port 10000 (Thrift) is listening.
  * Save the PID of the started Hive server, kill an already running Hive server to have a clean state for repeated test runs (tox).
* Some files received whitespace (especially the notebooks) and formatting changes due to updated linter dependencies.
* Some changes in `tox.ini` due to stricter rule for `passenv` and removed dependency-resolution flag.
