Bug description

When a player dies Essentials fails to handle the PlayerRespawnEvent do to the method Player.getRespawnLocation() not existing.

Steps to reproduce

Start up a server in any version from 1.16.1 to 1.20.3 (I used 1.16.5)
Add Essentials and EssentialsSpawn
Edit config:

respawn-at-home: true
respawn-at-home-bed: true

Restart the server
Use bed as player
Make player die

Expected behaviour

Player respawns at their bed without error

Actual behaviour

The player respawns at their bed, however it is due to the plugin failing to handle event resulting in an error to the console

Additional Information

EssentialsSpawn uses this condition in the EssentialsSpawnPlayerListener.java on line 52-56 to determine which method to use:

if(VersionUtil.getServerBukkitVersion().isHigherThanOrEqualTo(VersionUtil.v1_16_1_R01)) {
  respawnLocation = user.getBase().getRespawnLocation();
} else { // For versions prior to 1.16.
  respawnLocation = user.getBase().getBedSpawnLocation();
}

However I could not find Player.getRespawnLocation() in https://helpch.at/docs until version 1.20.4-R0.1 resulting in an Exception on servers.
