Related to #43

This pull request introduces enhancements to the "Today's Games" section by implementing redirect handling for the NHL schedule API request and adding a new page to display today's games.

• Modifies fetch_schedule_info in script-new.rb to handle HTTP redirects when requesting the NHL schedule API, ensuring the method follows redirects until the final destination URL is reached and parses the final response to extract games data.
• Adds a new ERB template file today.html.erb to display today's games in a clean table format, including game ID, start time, teams, and venue.
• Updates standings.html.erb to include a link to the new "Today's Games" page if there are games scheduled for today, enhancing the user experience by providing easy access to daily game schedules.
