tests: make sure pygments can detect python script without extension This .t file was failing for me when running run-tests.py with python3.11. Then I tried to run it with python3.10 and it failed anyway, even though it's the default python3 interpreter. But with `python3 ./run-tests.py` it worked fine. And this is what I found while looking at the way pygments lexer checks if a file without extension is likely to be a python script: shebang_matches(text, r'pythonw?(3(\.\d)?)?') Take guess why it doesn't work for python >= 3.10. To work around this issue, we can simply hardcode an "easier" shebang for pygments. This path to python interpreter obviously doesn't need to be accurate, since we're not running this script.
