Fix language strings plural suffixes unit test failing when executing JLanguageTest.php alone

[richard67]

Pull Request for Issue # .

Summary of Changes

This pull request (PR) fixes unit tests for the "getPluralSuffixes" function of JText currently failing when executed locally (at least on Linux).

No idea why they don't fail in drone CI.

The failure is caused by file "tests/unit/suites/libraries/joomla/language/data/language/en-GB/en-GB.localise.php" having not been adapted with PR #28763 .

In addition, this PR adds a missing test case for the "more than 1" case.

Testing Instructions

1. On a git clone, checkout and if necessary update the staging branch so it's up to date with the staging branch here.
2. Open a command window and change directory to the root folder of that git clone.
3. Run composer install.
4. Run ./libraries/vendor/phpunit/phpunit/phpunit ./tests/unit/suites/libraries/joomla/language/JLanguageTest.php
   Result: See section "Actual result BEFORE applying this Pull Request" below.
5. Revert all local changes by running these 2 git commands:
   git clean -d -x -f
git checkout .
6. Apply the changes from this PR.
7. Repeat steps 2 to 4.
   Result: See section "Expected result AFTER applying this Pull Request" below.

from code review looks good,
but unfortunately cannot run local unittest, do not have php 5 installed, and it somehow not work with 8

Patch works.

For people testing on Windows, make sure PHP is added to your system path variables.
Then use: php ./libraries/vendor/phpunit/phpunit/phpunit ./tests/unit/suites/libraries/joomla/language/JLanguageTest.php
