[zun] create pike-em tag against final releases

This is a procedural review to transition pike into extended maintenance by
creating the pike-em tag

It's possible that the release isn't needed (for example if there are no code
changes sine the previous release, sadly that's non-trivial to detect en masse.

If you are the PTL or release liaison for this team please +1 this review
if it is ready or -1 and take over the review to correct mistakes.
