Document that you need to add an extra JavaScript file when using extensions

[wimdeblauwe]

It was not clear to me from the docs at https://htmx.org/docs/#extensions that you need an extra JS included when you want to use an extension (like SSE support). Also the https://htmx.org/extensions/server-sent-events/ page makes no mention of this.

I also noticed that htmx itself has a minified version (htmx.min.js), but the extensions do not have this (only ext/sse.js for example).

The minification issue has a separate issue https://github.com/bigskysoftware/htmx/issues/1089
