Enhancment/url validator harsh

Added validateUrl utility

This check can be replaced with the isNullOrEmpty or isNullOrWhitespace utility method.

Limit to only consider "http/https" protocols might not be good for a validateUrl method, maybe renaming the method to isValidHttpUrl (this naming also matches the other validation methods like isObject, isValidGuid,...) might be better.

And at this point it might be good to have both, validateUrl and validateHttpUrl, and then one can reuse the other and do additional checks, something like:

export function isValidUrl(value?: string): boolean {
  try {
    new URL(value);
    return true;
  } catch {
    return false;
  }
}

export function isValidHttpUrl(value?: string): boolean {
  if (!isValidUrl(value)) {
    return false;
  }

  return value.startsWith("http://") || value.startsWith("https://");
}

what you think?
