RegionTeleport

Added /regionclear. This command allows you to clear specific entities from specific regions.

Available Types:
( ) are optional specifications
-all
-monsters
-animals
-ambient (bats)
-items(:<item name>)
-vehicles (Living vehicles like horses are excluded)
(all of the above are included in -all)
-displays (Only 1.19.4+)
-specific:<entity name>

The ones above don't clear npcs, named entities 
& tamed entities, to also clear those you can use:
-npcs(-only)
-tamed(-only)
-named(-only:[name])

The -only means only tamed entities will get removed, 
or only entities named "Steve" will get removed, etc.

Command examples:
/regionclear <region(s)> <types> (-s) (-w:[worldname])
/regionclear example1,example2 -animals -named:steve
/regionclear __global__ -animals -named-only:steve
/regionclear example1 -items:diamond,emerald -monsters -w:world_example

Specifying multiple sources is possible, so specifying 
"-monsters -vehicles -specific:block_display" will remove 
all monsters, all non-living vehicles and all block displays.

Moved /regiontp help message from the language file into the plugin directly. This was done to keep /regiontp help up to date at all times.

Fixed the default lang msg for console-wrong-usage showing the wrong format.

Some internal code changes:

• Java version & language is now 17.
• Updated dependency versions.
