Extensions don't provide minified version

[scrhartley]

htmx includes a minified version as part of its release on npm:
https://www.npmjs.com/package/htmx.org?activeTab=code

Extensions currently don't have a similar dist step and so only the non-minified version is available,
e.g. https://www.npmjs.com/package/htmx-ext-head-support?activeTab=code
This is noticeable since I was using a non-JS backend and the browser ended up with the non-minified file.
