Migrate expat from sourceforge to github
Summary
Build fails because a new version of expat is out.
Rationale
Builds should never fail when a new version of expat, or any other 3rd party component, is out.
Implementation Details
Expat is officially migrating from SF to GH since 2022-01-09.
Also, downloading expat packets from GH will be more resilient as the URLs aren't discarded every time a new version is out.
Note: at this moment, there exists a version 2.4.9, but this commit/MR only focuses on changing the official source repository.
