"git pull" warning on Ubuntu 26.04 client of git.sv.gnu.org

[Paul Eggert]

When I run the shell command "git pull" in my Emacs development 
directory, which is cloned from 
myusern...@git.sv.gnu.org:/srv/git/emacs.git, I see the following 
annoying behavior:

$ git pull
** WARNING: connection is not using a post-quantum key exchange algorithm.
** This session may be vulnerable to "store now, decrypt later" attacks.
** The server may need to be upgraded. See https://openssh.com/pq.html

Although I can silence the annoyance by following the instructions here:

https://www.openssh.org/pq.html

which effectively suggest that I put the following lines into 
$HOME/.ssh/config:

Host git.sv.gnu.org
        WarnWeakCrypto no-pq-kex

it would be nicer if I didn't have to do that.
