jordi fita mas 19bcfc29e8 Update HTMx version to 1.9.2 
I was hit with a couple of bugs: hx-on not properly de-initializing,
with a workaround in 43fffb68 and properly fixed with version 1.9.2;
and elements with naked hx-trigger did not work with hx-boost, as i do
for the tag inline form, fixed in 1.9.1.

The other bug fixed in 1.9.1, play well with other libraries that also
use the window.onpopstate, did not affect me, i believe.

jordi fita mas 4162da3a06 Force Content-Type to text/html when rendering a template 
By chance, i found out that sometimes Go returned a Content-Type header
of text/plain for some responses to HTMx request.  Go’s documentation
for http.ResponseWriter.Write sheds some light to this issue:

> If the Header does not contain a Content-Type line, Write adds a
> Content-Type set to the result of passing the initial 512 bytes of
> written data to DetectContentType.

http.DetectContentType has “sniff signatures” for the most common HTML
elements, such as `<BODY`, `<P`, or even `<!--`, but when the template
only has elements not in that list, the text “text sniff signature”
kicks in because the content does not contain binary data bytes, as
specified in [0], §7.1, step 9.

I can not change mustRenderTemplate’s wr parameter, and its callers’,
to be of type http.ResponseWriter because mustWriteInvoicePdf writes
the template to a pipe object, which is not of this type.  Thus, i have
to resort to type assertion inside the method.
