RangeUpgrade permissions check does not work correctly

Description

Describe the bug

Example permission in the config is incorrect. -

Upgrades/src/main/resources/config.yml

Line 18 in 1a38e1e

# "bskyblock.upgrades.range-upgrade.2"

Plugin is checking for permissions this way:

Upgrades/src/main/java/world/bentobox/upgrades/upgrades/RangeUpgrade.java

Line 101 in 1a38e1e

String permissionStart = gamemode + ".upgrades." + this.getName() + ".";

and name of the RangeUpgrade is "RangeUpgrade", not "range-upgrade". -

Upgrades/src/main/java/world/bentobox/upgrades/upgrades/RangeUpgrade.java

Line 26 in 1a38e1e

super(addon, "RangeUpgrade", "RangeUpgrade", Material.OAK_FENCE);

Expected behavior

Permissions in the config and in the code should be the same, because right now when giving permissions to the player, according to the config, player does not have possibility to upgrade his island's range.

Oops, you're right, however it's rangeupgrade since there is a .toLowerCase.

I'm fixing it in the config.
