Add automated test for "Name strategies test selected strategy"

The manual test is here: Name strategies test selected strategy [Since XWiki 12.0RC1].

The test verifies if testing the Naming strategy within Administration UI is done properly.

Ilie Andriuta: Hi! Continuing the manual tests migration, there is a test about checking if testing Naming strategy from Administration is done properly: https://test.xwiki.org/xwiki/bin/view/Administration%20Tests/Name%20strategies%20test%20selected%20strategy. I've checked https://github.com/xwiki/xwiki-platform/blob/73b07f8352d1716b9945b577d6e4a3334f058a77/xwiki-platform-core/xwiki-platform-model/xwiki-platform-model-validation/xwiki-platform-model-validation-default/src/test/java/org/xwiki/model/validation/script/ModelValidationScriptServiceTest.java but not sure if the corresponding automated tests exist. Can you please confirm?

Thanks!

 I can't find a reference to addNewCharacter (the button to add a new character to the set, which is used in the described manual test) or #createReplacementCharacterModal in the pageobjects of xwiki-platform, so it seems to me too that there's no corresponding automatic test 👍️

Ilie Andriuta: Thanks, Lucas Charpentier! ! I will create a task for it.
