Doubled bullseye version info on releases page

Hi,

on https://www.debian.org/releases we currently have

	"The current stable distribution of Debian is version 11, codenamed 
	bullseye. It was initially released as version 11 on August 14th, 2021 
	and its latest update, version 11.0, was released on August 14th, 2021."

So there is an unnecessary part at the end about point release (this did 
not happen yet).

This is because in ../english/template/debian/release_info.wml
<current_initial_release> is set to "11" instead of "11.0".

I will correct this shortly.
I have verified that this modification will not cause any harm at other
places of the website.
