nixos/nextcloud: sync nginx config with upstream

Upstream changes were checked by checking out the stable31 branch of the
https://github.com/nextcloud/documentation and comparing:

git diff c1c9b0a072537544769fdd6062989a631d4fb17c admin_manual/installation/nginx-root.conf.sample

Notably, this adds the text/javascript and application/wasm mime types to the list of
gzip'ed mime types, which improves nextcloud loading in our testing.

Also adds webp support.
