Show HN: A Raycast script for the HN bookmarklet

Since Arc doesn't have bookmarks, this became the best way for me to post.

``` #!/bin/bash

  # Required parameters:
  # @raycast.schemaVersion 1
  # @raycast.title Submit to Hacker News
  # @raycast.mode fullOutput

  # Optional parameters:
  # @raycast.icon ./images/yc.png
  # @raycast.packageName Web Tools
  # @raycast.argument1 { "type": "text", "placeholder": "URL to submit", "percentEncoded": false }

  # Documentation:
  # @raycast.description Submit a URL to Hacker News with the current page title.
  # @raycast.author DigitalNoumena

  # Extract the <title> tag
  page_title=$(curl -sL "$1" | sed -n 's:.*<title>\(.*\)</title>.*:\1:p')

  # If no title is found:
  if [ -z "$page_title" ]; then
    page_title="No title found"
  fi

  # URL encode the title and the URL
  encoded_url=$(echo -n "$1" | jq -sRr @uri)
  encoded_title=$(echo -n "$page_title" | jq -sRr @uri)

  # Open the Hacker News submission page with the encoded URL and title
  open "https://news.ycombinator.com/submitlink?u=$encoded_url&t=$encoded_title"

```
