Setting allow_archive_path_syntax was marked as experimental

The setting allow_archive_path_syntax was marked as experimental by mistake. Add a test to prevent having experimental settings enabled by default. #79320 (Alexey Milovidov).
The setting allow_archive_path_syntax was incorrectly marked as experimental and has now been corrected to no longer be experimental by default. A test was also added to ensure that no experimental settings are enabled by default in the future.

Why it matters

This change prevents confusion and potential misuse by clarifying the status of the allow_archive_path_syntax setting, ensuring it is treated as a stable, supported feature rather than experimental. It improves configuration reliability and user experience by enforcing proper classification and detection of experimental settings.

How to use it

No special action is required by users. The allow_archive_path_syntax setting is now stable and enabled according to standard configuration without being marked as experimental. This ensures consistent behavior without needing to set or toggle any experimental flags.
