Merge bitcoin/bitcoin#22201: test: Fix TestShell to allow running in Jupyter Notebook
168b6c317ca054c1287c36be532964e861f44266 add dummy file param to fix jupyter (Josiah Baker)
Pull request description:
this fixes argparse to use `parse_known_args`. previously, if an unknown argument was passed, argparse would fail with an `unrecognized arguments: %s` error.
## why
the documentation mentions being able to run `TestShell` in a REPL interpreter or a jupyter notebook. when i tried to run inside a jupyter notebook, i got the following error:

this was due to the notebook passing the filename of the notebook as an argument. this is a known problem with notebooks and argparse, documented here: https://stackoverflow.com/questions/48796169/how-to-fix-ipykernel-launcher-py-error-unrecognized-arguments-in-jupyter
## testing
to test, make sure you have jupyter notebooks installed. you can do this by running:
```
pip install notebook
```
or following instructions from [here](https://jupyterlab.readthedocs.io/en/stable/getting_started/installation.html).
once installed, start a notebook (`jupyter notebook`), launch a python3 kernel and run the following snippet:
```python
import sys
# make sure this is the path for your system
sys.path.insert(0, "/path/to/bitcoin/test/functional")
from test_framework.test_shell import TestShell
test = TestShell().setup(num_nodes=2, setup_clean_chain=True)
```
you should see the following output, without errors:
