Workaround symbol resolution bug in Clang 19

Clang 19 seems to see the old usage of
absl::string_internal::HasAbslStringify in GoogleTest 1.14.0 and
incorrectly resolves absl::HasAbslStringify sometimes. This issue is
fixed when a version of GoogleTest that removes
absl::string_internal::HasAbslStringify is used.

This workaround is ugly but will be removed after the next GoogleTest
release.
