where can I subscribe to gnu.emacs.announce mailing list, mirrored

It's not a mailing list, but a usenet newsgroup. You can read it directly
using a newsreader via nntp, supported e.g. by gnus, thunderbird and
many other newsreaders.
You don't have to use google groups, it's just a gateway.
However, many of the gnu usenet groups also do have a gateway to
mailing lists:
http://lists.gnu.org/
This one could be the gnu.emacs.announce mailing list:
http://lists.gnu.org/mailman/listinfo/info-gnu-emacs
If this is, what you prefer.
