docs: A new "Using Ask Fern" section was added between the "Setup" and "Configuration" sections, which explains the three different ways users can interact with the bot: using the `/fern` command, mentioning the bot with `@Ask Fern`, or asking questions naturally in configured channels. This addition provides clearer guidance on how to actually use the bot after installation. #1461
