[doc] ideomorph htmx import instructions outdated

[jackielii]

The docs on idiomorph is out dated. The idiomorph read me says: https://github.com/bigskysoftware/idiomorph?tab=readme-ov-file#htmx

Idiomorph was created to integrate with htmx and can be used as a swapping mechanism by including the dist/idiomorph-ext.js file in your HTML:

or by importing the "idiomorph/htmx" module: import "idiomorph/htmx";

However https://htmx.org/extensions/idiomorph/ says:

import htmx.org;
import idiomorph;

Looks like this didn't get automatically closed for some reason. Should be manually closed I guess.
