url.searchParamsSymbol may affect the benchmark results of URLSearchParams.sort()

[kylo5aby]

The benchmark script url-searchparams-sort.js currently utilizes searchParamsSymbol to create key-value pairs for URLSearchParams, but it has been removed since Node.js version 20.x. This removal may have an impact on the benchmark results, potentially affecting comparisons, such as between versions 18.x and 21.x.
