Fix: prevent duplication of "invalid index name" string in the final exception error message (#130027)

* Use `throwInvalidIndexNameException()` to throw invalid ex after
dropping asterisk in `IdentifierBuilder#resolveAndValidateIndex()`

* Assert the message in test

* Refactor

* drop invalid chars from assertion string due to randomisation issue

* Re-assert invalid chars

* Update docs/changelog/130027.yaml
