[PATCH] treewide: replace /usr/bin/python3 shebangs with env python3

[PATCH] treewide: replace /usr/bin/python3 shebangs with env python3

[Oli R]

Use /usr/bin/env python3 instead of hardcoded interpreter paths
to improve portability across environments where python3 is not
installed in /usr/bin.

No functional changes intended.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] Commit message states it replaces `#!/usr/bin/python3` shebangs and causes no functional changes, but actually changes `#!/usr/bin/python` to `#!/usr/bin/env python3` in `tools/perf/tests/shell/lib/perf_json_output_lint.py`.

Could this affect functionality on systems where python defaults to Python 2
or is managed differently?

The change looks good to me, but I wonder it should be split into
separate patches for the different subsystems. We do not care about
Python 2, so I think some review prompt improvements are necessary.

Thanks!
