mailman3-web logs too much data

in #40471 (closed), we focused on upgrading the mailman server from legacy, which we did. in doing so, we kept some of the current warts, which in the case of this issue that the server logs too much.

i've tried to tweak the logging by changing the levels of the root logger in the settings.py file, but it seems like it didn't work, we're still getting this garbage:

==> /var/log/mailman3/web/mailman-web.log <==
[pid: 3622165|app: 0|req: 67/67] REDACTED () {64 vars in 1455 bytes} [Tue Nov  5 18:35:59 2024] GET /mailman3/hyperkitty/list/tor-consensus-health@lists.torproject.org/2024/2/ => generated 190498 bytes in 97 msecs (HTTP/1.1 200) 8 headers in 390 bytes (1 switches on core 0)

we need to figure out a way to disable this. it's possible this is in the uwsgi.ini instead, as it also seems to talk to mailman-web.log.
