Rollback of commit eb01c21f94fbd6119c2f73796f63f789fd765910.

*** Reason for rollback ***

This change broke internal docs and is no longer needed because the
documentation pipeline will automatically take care of converting these to
.html
for the external site.

*** Original change description ***

Fix links in http://bazel.io/docs/skylark/
