The original software engineering course from UBC was not available, and hence was temporarily switched to a Coursera course without any discussion. The original course is now once again available, so we should switch back to it.
This change is adding the interactive, open-source, community-led SICP version that was adapted into JavaScript.
This addition seems worthwhile because JavaScript may be a more appealing language to go through SICP with than the original Scheme. In addition, this JavaScript version of SICP was created with the apparent goal of being as close to the original Scheme version as possible:

The Py4E course link in the intro cs coursepage was not marked as link. While GitHub renders it as link, the GitHub pages website don't. This PR fixes that.
The PR also fixes the CS50P discord invite link, which was expired. This time, I have made a link that never expires, and can be used an unlimited number of times.

* Hopefully fix some confusions regarding alt courses
Mention the full word "alternative" instead of the short form "alt" which may cause confusion to non-native speakers. Also change "/" to "," for the two parts of HTC course.
* Fixed the missing "alt"
