Doc: replace \target with \keyword if at start of page

A \target whose purpose is to link to the top of a
page (and not to a section within a page) works better
as a \keyword, because \target generates a
new html anchor which, in this case, is not tied to
any title element on the page.
A \keyword links to the page itself, as expected.
