use setAttribute instead for hx-disable

here

you are setting with `el.disabled = true` but this only works on inputs, not div, sections, etc. If I want to do a css selection on the disabled state to hide specific content that is not input, I can't

open to do PR, just agree on the approach

Read src/htmx.js at lines 1767-1779, linked in the issue, and trace the hx-disable handling. Verify the disabled state can be selected on div and section elements as well as inputs; done means the requested behavior works consistently across those elements.
