Small grammar tweaks in export sections of org.texi

* org.texi The sections in the Exporting section of the manual left
out articles in the description of the org-export-as-* commands, among
other places. This patch adds them, adds a few missing prepositions,
and switches instances of "an HTML" to "a html" for internal
consistency.
