fix: information disclosure bug in preconditions GET (#19810)

precondition check was being honored before, validating if anonymous access is allowed on the metadata of an object, leading to metadata disclosure of the following headers. ``` Last-Modified Etag x-amz-version-id Expires: Cache-Control: ``` although the information presented is minimal in nature, and of opaque nature. It still simply discloses that an object by a specific name exists or not without even having enough permissions.
