Apparent Typo in config.json - actions > update-command [Bug]

[Svra44]

Describe the bug

Using "config.json" as sourced from "/etc/xdg/swaync/config.json" I observed that "type": "toggle" such as the example "nmcli radio wifi" toggle wasnt working as expected.
Saw that "update_command" is in the "config.json", however ReadMe & Man indicate it should instead be "update-command". Switching to "update-command" looks to have fixed the toggle behaviour.
https://github.com/ErikReider/SwayNotificationCenter/blob/main/src/config.json.in has the same underscore for "update_command".

-- Example from "config.json" at current
{
"label": "直",
"type": "toggle",
"active": true,
"command": "sh -c '[[ $SWAYNC_TOGGLE_STATE == true ]] && nmcli radio wifi on || nmcli radio wifi off'",
"update_command": "sh -c '[[ $(nmcli radio wifi) == "enabled" ]] && echo true || echo false'"
}

To Reproduce

Steps to reproduce the behavior:

1. Use the "config.json" as provided in repo or package
2. Toggles will not work correctly and becomes desync'd with the actual status reported by nmcli, as "update_command" is not executed.

Expected behavior

"config.json" needs to be corrected to use "update-command" instead of "update_command" for toggle status to be accurate. Doing so causes "update-command" to get executed correctly.
