f6eadaa Use same Python executable for subprocesses as for all-lint.py (Kristaps Kaupe) Pull request description: Before this all linters were ran by `/usr/bin/env python3`, no matter what was used to run `test/lint/all-lint.py`. This change allows to use non-default Python executable for `test/lint/all-lint.py` and then all subprocesses will also use same Python interpreter (for example, `python3.10 ./test/lint/all-lint.py`). See bitcoin#26792 (comment) as use case.
