[GSoC][PATCH 5/5] t: add test for git refs optimize subcommand

From: Meet Soni <meetsoni3017@gmail.com>

Message-ID: <20250826073645.1074397-6-meetsoni3017@gmail.com>
In-Reply-To: <20250826073645.1074397-1-meetsoni3017@gmail.com>

Add a test script, `t/t1463-refs-optimize.sh`, for the new `git refs optimize` command.

This script acts as a simple driver, leveraging the shared test library created in the preceding commit. It works by overriding the `$pack_refs` variable to "refs optimize" and then sourcing the shared library (`t/pack-refs-tests.sh`).

This approach ensures that `git refs optimize` is tested against the entire comprehensive test suite of `git pack-refs`, verifying that it acts as a compatible drop-in replacement.
