[PATCH v3 2/2] [Outreachy][Patch v1] t3404: employing test_line_count() to replace test

["Usman Akinyemi via GitGitGadget" <gitgitgadget@gmail.com>]

From: Usman Akinyemi <usmanakinyemi202@gmail.com>

Refactor t3404 to replace instances of `test` with `test_line_count()`
for checking line counts. This improves readability and aligns with Git's
current test practices.
