Update scrapping ant error handling

[ivanovvladi]

Thanks for creating and maintaining this helpful tool

I noticed that scrapping ant sends 423 code with a message

Our browser was detected by target site. Retry the request or try adjusting proxy country, proxy type and browser rendering settings. Our documentation: https://docs.scrapingant.com/ and support email: support@scrapingant.com

and a request doesn't fall into the catch -> retry block. Hence, I'm opening this PR to update the error handling

If the status message is not a number, this would generate an exception no?

Thanks for reviewing the PR. That was my first impression, too; however, it returns

    /**
     * A value that is not a number.
     * In equality comparisons, NaN does not equal any value, including itself. To test whether a value is equivalent to NaN, use the isNaN function.
     */
    readonly NaN: number;

and the if-else block is evaluated as expected. Since I'm not fully proficient with JS, there might be development standards that defer from the implementation. Let me know if that's the case, and I'd be happy to change it.
