uptime parser with 0 user(s) on ubuntu 24.04 docker not matching

[lts-po]

Problem

When running ubuntu 24.04 in docker uptime reports "0 user" so the parser will not match. Looks like its updated to say "user" instead of "users" when <=1, which the parser is using for matching.

Steps to reproduce

docker pull ubuntu latest
docker run --rm -ti ubuntu bash

in docker:

$ apt update && apt install -y jc

$ uptime
 12:44:19 up 1 day, 23:12,  0 user,  load average: 3.94, 4.43, 2.75

$ uptime | jc --uptime -d

Fix Change match on 'users' to 'user' to catch both: https://github.com/kellyjonbrazil/jc/blob/master/jc/parsers/uptime.py#L165

Example output with patch:

$ uptime | jc --uptime
{"time":"12:51:06","uptime":"1 day, 23:18","users":0,"load_1m":0.25,"load_5m":1.28,"load_15m":1.83,"time_hour":12,"time_minute":51,"time_second":6,"uptime_days":1,"uptime_hours":23,"uptime_minutes":18,"uptime_total_seconds":170280}
