Mistake in Tags.md

[dominikh]

From http://rubydoc.info/docs/yard/file/docs/Tags.md:

@api: Declares the API that the object belongs to. Does not display in output, but useful for performing queries (yardoc --query). Any text is allowable in this tag, and there are no predefined values

That's not exactly true, however, since @api private will in fact cause a special note in the produced documentation.
