* fix docs suggestions
There are two different types of changes in this PR:
- H1s should use ATX headers (`#`)
- tables should have a header row that is not empty.
* replace docs links with source
This addresses another docs build warning. The docs build system flags absolute links to the pages on docs.microsoft.com as warnings, which should be replaced with relative links. This fix changes the link to the source doc on GitHub. I'm currently looking for a better solution.
* Revert "replace docs links with source"
This reverts commit b40cfc9632.
Fixesdotnet/docs#6335
Because these are in a code fence, the back-slash was rendering on the docs platform. This still renders correctly in GFM, and on docs.

* Initial port of the C# 6 specification; all the heavy lifting had been done by @ljw1004
* Remove pdf, html versions and grammar versions until we figure out how to build them.
