Describe the bug
Can't load config file while PlayerKills.CommandsOnKill section was set with commands containing something like '.

To Reproduce
Steps to reproduce the behavior:

1. Set section PlayerKills.CommandsOnKill with minecraft:give <player> minecraft:name_tag{display:{Name:'"=TITLE="',Lore:['"LINE ONE"','"LINE TWO"']}} 1.
2. Then reload it.

Expected behavior
The config backup file (config.old.yml) will be loaded, what we set won't in effect.

Plugin and Server version
Server: paper-1.18.1
Pugins: 3.9

Additional context
I tried change commands to minecraft:give <player> minecraft:name_tag{display:{Name:\'"=TITLE="\',Lore:[\'"LINE ONE"\',\'"LINE TWO"\']}} 1, and it still doesn't work.

That's unrelated to this plugin, it's due to how yaml parses the config files, you could use a yaml validator like this https://onlineyamltools.com/validate-yaml to help solve the issue. I'm not sure how to make that work.

Thanks for your suggestion!
It's truly YAML grammar error, I change my config with something like below:

Player Kills:
  Money Reward: 0
  Money Penalty: 0
  Money Steal: false
  Commands On Kill: >-
    minecraft:give <player> minecraft:name_tag{display:{Name:'"=TITLE="',Lore:['"LINE ONE"','"LINE TWO"']}} 1
  WorldGuard Exclusions:
    - 'exampleregion'

>- means next line is a string data without line warp, this kind of usage don't need quotations to indicate data type.
