Debian 8 Jessie archive.debian.org GPG error KEYEXPIRED since 2022-11-19 (what now?)

Since 19 november 2022 apt-get update on Debian 8 Jessie gives the follwowing error/warning when running apt-get update:

W: GPG error: http://archive.debian.org jessie Release: 
The following signatures were invalid: KEYEXPIRED 1587841717

The contents of my /etc/apt/sources.list:

deb http://archive.debian.org/debian/ jessie main contrib non-free
deb http://deb.freexian.com/extended-lts jessie-lts main contrib non-free

The expired keys:
apt-key list

/etc/apt/trusted.gpg.d/debian-archive-jessie-automatic.gpg
pub   4096R/2B90D010 2014-11-21 [expired: 2022-11-19]
uid   Debian Archive Automatic Signing Key (8/jessie) <[email protected]>

/etc/apt/trusted.gpg.d/debian-archive-jessie-security-automatic.gpg

I have the debian-archive-keyring package installed.

I tried to update the keys, using:

gpg --keyserver keyring.debian.org --recv-key 2B90D010
gpg --keyserver keyring.debian.org --recv-key C857C906

But these keys do not seem to be known on keyring.debian.org:

gpg: requesting key 2B90D010 from hkp server keyring.debian.org
gpgkeys: key 2B90D010 can't be retrieved
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

gpg: requesting key C857C906 from hkp server keyring.debian.org
gpgkeys: key C857C906 can't be retrieved
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0`

So I suppose my questions are:

All keys on the archive.debian.org site are expired.

1. Am I trying to update the keys against the correct keyserver (keyring.debian.org)?
2. If that is not the issue, then will somebody at Debian fix this (update and publish keys)?
3. If no, then is there a way to get rid of the warnings when apt-get update and apt-get install are run?
