Monit summary command no longer works with newer version of monit

Description of Issue

Monit has upgraded the output of the summary command to present a new table. I can't remember what it looked like before, but I believe it was a much simpler text output (there certainly wasn't a drawn table).

This appears to have broken the Salt monit summary command.

Setup

I don't believe any custom setup is required other than Monit to be installed. The version I have is 5.26.0. I'm afraid I don't know which version triggered the change, other than it appears to be between version 5.2.5 (which comes with Amazon Linux V1 base AMI) and 5.26.0 which is the latest.

Steps to Reproduce Issue

Here's the output of running monit summary on the machine, not via Salt:

[root@hostname ~]# monit summary
Monit 5.26.0 uptime: 9d 5h 12m
┌─────────────────────────────────┬────────────────────────────┬───────────────┐
│ Service Name                    │ Status                     │ Type          │
├─────────────────────────────────┼────────────────────────────┼───────────────┤
│ hostname goes here    ...       │ OK                         │ System        │
├─────────────────────────────────┼────────────────────────────┼───────────────┤
│ rootfs_inodes                   │ OK                         │ Filesystem    │
└─────────────────────────────────┴────────────────────────────┴───────────────┘

And here's the output of running it via Salt:

[root@hostname ~]# salt 'hostname' monit.summary
hostname:
    ----------

It can still be run manually, but the command is a bit more of a mouthful:

[root@hostname ~]# salt 'hostname' cmd.run "monit summary"
hostname:
    Monit 5.26.0 uptime: 9d 5h 12m
     Service Name                     Status                      Type
     hostname...                      OK                          System
     rootfs_inodes                    OK                          Filesystem

Start in salt/modules/monit.py around lines 102-132, especially 122-131, and reproduce monit.summary with Monit 5.26.0. Trace how the new table output is processed and verify that Salt returns the summary rather than an empty result; done means the command works with the newer output format.
