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.
