EDB builds Postgres 13 with an obsolete ICU version

Hi,

As a follow-up to bug #16570 [1] and other previous discussions
on the mailing-lists, I'm checking out PG13 beta for Windows
from:
https://www.enterprisedb.com/postgresql-early-experience
and it ships with the same obsolete ICU 53 that was used
for PG 10,11,12.
Besides not having the latest Unicode features and fixes, ICU 53
ignores the BCP 47 tags syntax in collations used as examples
in Postgres documentation, which leads to confusion and
false bug reports.
The current version is ICU 67.

I don't see where the suggestion to upgrade it before the
next PG release should be addressed but maybe some people on
this list do know or have the leverage to make it happen?
