During the upgrade I see this message:

php7.4 /var/www/pixelfed/composer.phar update -d /var/www/pixelfed --no-interaction --no-ansi
DEBUG Do not run Composer as root/super user! See https://getcomposer.org/root for details
DEBUG Loading composer repositories with package information
DEBUG Warning from https://repo.packagist.org: Support for Composer 1 is deprecated and some packages will not be available. You should upgrade to Composer 2. See https://blog.packagist.com/deprecating-composer-1-support/

What should we do ? 🤔

Upgrade also takes up to ~5GB of memory in my case… people might need a lot of swap to make it work.

Usual CI "issues", I don't know if we should care about them… let's merge and try again on testing.
