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"
* Fix machine learning in core applications
The machine learning course is only 3 weeks long, not 11. Further, it's a very gentle introductory course. Even the prerequisite of Basic coding is stretching it, but it is as listed on the course page.
* Fix machine learning
Machine learning should link to the entire specialization. The specialization is 11 weeks in all I believe, and they suggest 9 hours per week although that could be scaled down to 4-6 hours if you're just auditing. Also, the prerequisite should be basic coding, linear algebra is not necessary.
Closes#1118
