Change internal links using [.element] syntax to [element] syntax.

This is supported by intellij/studio and docs generation while the "." syntax is not.

Change-Id: I12aa77290a01439e505b9b134afc2243b1a308e8
Test: docs-only change. Open in studio and find colorization is fixed. Docs generation passes.
