Subject: [GSoC][PATCH v2 4/4] t: add test for git refs exists subcommand

From: Meet Soni <[email-masked]>
Date: Sat, 23 Aug 2025 11:30:12 +0530

Add a test script, `t/t1462-refs-exists.sh`, for the `git refs exists`
command.

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

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