Improve URL checks to reduce false-negatives

This commit improves the URL health checking mechanism to reduce false
negatives.

- Treat all 2XX status codes as successful, addressing issues with codes
  like `204`.
- Improve URL matching to exclude URLs within Markdown inline code block
  and support URLs containing parentheses.
- Add `forceHttpGetForUrlPatterns` to customize HTTP method per URL to
  allow verifying URLs behind CDN/WAFs that do not respond to HTTP HEAD.
- Send the Host header for improved handling of webpages behind proxies.
- Improve formatting and context for output messages.
- Fix the defaulting options for redirects and cookie handling.
- Update the user agent pool to modern browsers and platforms.
- Add support for randomizing TLS fingerprint to mimic various clients
  better, improving the effectiveness of checks. However, this is not
  fully supported by Node.js's HTTP client; see nodejs/undici#1983 for
  more details.
- Use `AbortSignal` instead of `AbortController` as more modern and
  simpler way to handle timeouts.
