Huge update - tons of changes, additions and fixes

Functional changes

• Added support for version 1.21.5
• Updated information about available commands (/prx help)
• Added NL language. Thanks to LegacyHeaven
• Added ability to set up a Webhook for Discord

Config e.g.:

webhook:
  discord:
    enabled: false
    url: "YOUR_WEBHOOK_URL_HERE"

• Added PunisherXAPI version 1.0-Beta - more info in Wiki
• Added placeholders for mute, warn and jail penalty times

  • From now on, the following placeholders are available:

    • %prx_mute_remaining_time%
    • %prx_warn_remaining_time%
    • %prx_jail_remaining_time%
    • %prx_total_active_punishments%
    • %prx_total_punishments%

  • Additionally, in the language file in the placeholders category, you can set any format in which they will be displayed.

For example:

placeholders:
  mute_remaining_time: "<gray>Muted until: <gold>"
  warn_remaining_time: "<gray>Warning valid until: <gold>"
  jail_remaining_time: "<gray>Jail time remaining: <gold>"
  total_punishments: "<gray>Total punishments: <gold>"
  total_active_punishments: "<gray>Total active punishments: <gold>"

• Corrected the syntax of the /setjail command which now looks like this: /setjail <radius>

Include this in your language file so that it looks correct, e.g.:

setjail:
  usage: "Correct usage is: <gold>/setjail <radius></gold>"

• Teleporting the player on login when offline "jail" has expired
  • Teleportation location to be set in config file
• Added /setspawn command for more convenient respawn location setting after serving a prison sentence
• Added information about the new version in the chat
• All libraries, dependencies, and Kotlin and Gradle themselves have been updated to the latest versions

Fixed:

• Fixed the problem with the error Integer value is too big for SQLite
• Hotfix for removing active warnings
• Hotfix: Issue Closes #34

Technical changes:

• Changed maximumPoolSize settings for MySQL connections
• Added helper methods for setting spawn location after prison sentence
• Replacing ConcurrentHashMap with the efficient and optimal Caffeine cache library
• Added centralized class to manage all permissions in the plugin - change of permission system
  • From now on, the plugin switches to permissions according to the plugin.type.type.parameter standard, e.g. punisherx.cmd.ban
  • Backward compatibility has been ensured with simultaneous information about the need to update permissions on your server
• Added getSmartMessage method to handle multi-line messages for Broadcast

For example::

jail:
  broadcast: "<dark_gray>Player <gray>{player}</gray> has been jailed for <gray>{reason}</gray> for <gray>{time}</gray></dark_gray>"
  # Alternatively, you can use the message format below if you wish to further emphasize this message
  # broadcast:
    #- "<dark_gray>*************** Your Server Name *************** </dark_gray>"
    #- ""
    #- "<red>   Player <white>{player}</white> has been locked up</red>"
    #- "   Reason: <white>{reason}</white>"
    #- "   Duration: <white>{time}</white>"
    #- ""
    #- "<dark_gray>*************************************************** </dark_gray>"
