after communicating with the Raycast team (thanks Sorin), they added API for
1. Getting the latest version of Raycast via REST endpoint https://releases.raycast.com/releases/latest
2. Versioned download in the format of https://releases.raycast.com/releases/<version>/download
This update deprecates download via internet archive and switches to official download API
* raycast: init at 1.48.9, change github release url to internet archive url
* raycast: adding documentation explaining the reason we are using Internet Archive URL
* raycast: add lovesegfault to maintainers
