[facet html] Add surrounding div with "facetBody" class to "has_text" facet.
This makes its html structure consistent with the other facets
and fixes both css and a javascript behaviour (hide the facet body
when clicking on its title).
Closes #3797501.

----------
RSS is a pretty useful technology that can be widely used on this
site. Any set of data can be presented as RSS. You can then plug in
an RSS reader into that and follow the site activity. For example :
:raw-html:`<p><a class="reference"
href="view?vid=rss&rql=Any+X%2CM+WHERE+X+modification_date+M+ORDERBY+M+DESC+LIMIT+30"><img
alt="rss" src="data/rss.png"> latest changes</a></p>`
