[PATCH v2 7/9] t1900: cover repo info path keys and path-format

["Eslam reda ragheb via GitGitGadget" <gitgitgadget@gmail.com>]

From: Eslam reda ragheb <eslam.reda.div@gmail.com>

Extend t1900 to validate category-key expansion, path.* key
behavior, and --path-format handling for git repo info.

The tests compare repo info output to equivalent rev-parse values.

This ensures behavior remains aligned with existing plumbing
semantics.

Also keep mixed key/category ordering coverage so callers can rely
on deterministic output order when combining explicit keys with
category requests.
