Link Helper for GitHub issues

When user in a Telegram chat sends an issue number (e.g. #325) then this bot will send a message with a link to that issue number on GitHub.

Setup

1. Install ASP.NET Core Runtime 6.0
2. Set all values in the BotConfiguration section in appsettings.json

• BotToken: The token Telegram BotFather gave you for your bot
• BotHostAddress: The https address where this app runs on. It must have SSL certificate since Telegram requires that (LetsEncrypt works great)
• GitHubRepoOwner: Your GitHub username, or the name of your organization
• GitHubRepoName: The name of your GitHub repo
• DropPendingUpdates: When setting Telegram's webhook to call your app, drop all existing messages that have not been handled yet (i.e. don't handle past messages)
