Make Groups renderable (#181)

This change makes the result of `Group` renderable directly, instead of
panicking, with the important caveat that root-level attributes are
_ignored_. I don't think this will give problems in practice, as the
main use case for rendering `Group` is basically to return root-level
elements to the client using something like HTMX.

I tried adding a `Fragment`, but it was weird and confusing having two
functions (`Group` and `Fragment`) do essentially the same thing, the
only difference being whether the argument was a slice of `Node`s or
varargs.

Fixes #162
