Reject empty query and fragment delimiters.

URL.search and URL.hash are empty for URLs ending in ? or #. These values pass validation, but the appended endpoint becomes a query or fragment instead of a path. Reject the delimiters or remove them before returning the URL. (url.spec.whatwg.org)

Review comment at @bin/testObservability/helper/constants.js at line 23:
Update the URL validation condition that checks parsed.search and parsed.hash to
also reject trailing empty query or fragment delimiters, or remove those
delimiters before returning the URL, so appending the endpoint always extends
the path.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

Remove the URL value from every validation error.

remoteReporterApiUrl() propagates these errors, and runs.js logs the caught error through a console transport without redaction. A credential-bearing URL can therefore appear in build logs. Apply the same change to the parse and HTTPS validation errors.

Remove URL values from validation errors 
-    throw new Error(`${name} must be a valid https:// URL, got "${value}"`);
+    throw new Error(`${name} must be a valid https:// URL`);
...
-    throw new Error(`${name} must be an https:// URL, got "${value}"`);
+    throw new Error(`${name} must be an https:// URL`);
...
-    throw new Error(`${name} must not contain a query or fragment, got "${value}"`);
+    throw new Error(`${name} must not contain a query or fragment`);
Committable suggestion

IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Review comment at @bin/testObservability/helper/constants.js at line 24:
Update the URL validation errors in the helper that throws the query-or-fragment
error, along with its parse and HTTPS validation errors, to omit the supplied
URL value. Keep the validation-specific messages and error behavior unchanged.
