Document/suggest using helper functions to generate attributes #141
Description
A common request is to add special casing to html attribute generation (#33, #57, #105). We should document/link to datastar's builtin helpers. And document how you can create your own.
Also, if anyone is up for it, creating separate htpy-alpinejs and htpy-htmx packages that has nice, typed helpers that we could link to would be nice. I think there are a lot of overlap with htpy and htmx, Alpine.js and Datastar users. :)
