[PATCH v2 0/2] t5403: improve post-checkout hook testing

Following up on the recently merged patch that replaced 'test -f' with test_path_is_file, this series continues the cleanup of the post-checkout hook tests.

Patch 1/2 introduces a check_post_checkout helper function to replace the repeated pattern of reading and validating hook arguments. This refactoring does not change test behavior, but makes the code easier to maintain and prepares it for further improvement.

Patch 2/2 updates the helper and hook output format to use test_cmp instead of individual test commands. This provides clearer error messages on failure, making it easier to see which argument (old ref, new ref, or flag) did not match the expectation

Changes since v1:
- Updated the check_post_checkout helper comment to be more descriptive.
