config.sample.yaml: change default reply-to format

It previously was:

	<f_> hi everyone, what's up? I'm about to migrate some stuff today
	~ a while after ~
	<f_[mtrx]> <f_> "hi everyone,..." <- hi, doing great!

Now it is:

	<f_> hi everyone, what's up? I'm about to migrate some stuff today
	~ a while after ~
	<f_[mtrx]> f_: "hi everyone,..." <- hi, doing great!

Some IRC clients may not create a ping when the nickname is surrounded
with `<` and `>`.
