t/t2107-update-index-basic: use test_path_is_missing

From: jayesh0104 <[email protected]>

Replace a raw '! test -f' check with test_path_is_missing to use the standard test helper and improve consistency with other tests.

---
[GSoC]: t2107-refs-tests: drop '-f' from test_path_is_missing

High-level (Intent & Context)
=============================

The test script t/pack-refs-tests.sh has two issues that prevent it from running correctly.

It uses: ! test -f .git/index.lock

This is inconsistent with the Git test framework, where helper functions such as test_path_is_missing should be used instead of raw test checks.

Low-level (Implementation & Justification)
==========================================

Without sourcing test-lib.sh, the test framework is not initialized, leading to errors such as: test_expect_success: not found

Replaced raw file check with the appropriate helper:

- ! test -f .git/index.lock
+ test_path_is_missing .git/index.lock

Summary
=======

Replace test_path_is_missing .git/index.lock
