Multi-line attributes are not supported

[joerdav]

Brought to my attention by @c-nv-s in the HTMX discord.

When writing hyperscript it is common to have an attribute with multiple lines, such as:

data-script="on click
                do something
             end"

In this case an error is returned "string literal not terminated"

A workaround for this for now would be to use a go string literal:

data-script={`on click
                do something
             end`}
