This patch attempts to fix the broken docs by having the series
name match the branch name (2023.1 instead of 2023.1.antelope)
A patch was previously merged and reverted[0]. It changed the
name of the series, but missed updating the directory names
under the www directory.
I did test this locally, and it did correctly pupulate the pages
with links for the various projects, but I do not know if it
fully resolves the issue.
Additionally adds redirects for /2023.1.antelope to /2023.1
and 2023.2.bobcat to 2023.2.
