Change links on docs page to go to readthedocs (#99)

Fixes #94

The Slang docs will now be located at https://docs.shader-slang.org on ReadTheDocs. This change updates the links on https://shader-slang.org/docs/ to go to the relevant sections/pages of the RTD site instead of the GitHub Pages docs sites.
