BUG: grep: Invalid option -- P when running spin lint on macOS #29538
Description
Describe the issue:
When running spin lint on macOS, the command fails with the following error.
It seems that the grep command on macOS (BSD grep) does not support the -P option (Perl-compatible regex), which is available on GNU grep. This causes the linting step to break out of the box.
Lightning-AI/pytorch-lightning#19938 is a similar issue.
Reproduce the code example:
$ spin lintError message:

All checks passed!
