[PATCH v2] test-lib-functions.sh: fix test_grep fail message wording

[Shreyansh Paliwal <shreyanshpaliwalcmsmn@gmail.com>]

From: shreyp135 <shreyanshpaliwalcmsmn@gmail.com>

In the recent commit
2e87fca189 (test framework: further deprecate test_i18ngrep, 2023-10-31),
the test_i18ngrep() function was deprecated.

So if a test employing this function fails,
the error messages may be confusing due to wording issues.

It's important to address these wording changes to ensure smooth transitions
for developers adapting to the deprecation of test_i18ngrep,
and to maintain the effectiveness of the testing process.
