More robust way to get git contributions graph

[LAMaglan]

Currently getting from a old, unmaintained github repo/website:
https://ghchart.rshah.org/

Try to use the Github API (would require authentication, own code for visualizing, etc)

[LAMaglan]

Actually, authentication is not required for the endpoint that has all the data for "public" commits:

https://api.github.com/users/LAMaglan/events

No need to make any changes while ghchart works
