[HarshMehta112]

Problem

Resolves : #8281

Solution

• Updated ExprLocationOf.java to support OfflinePlayer directly

• Added @Since annotation for INSERT version (offline players)

Tests

  • location of {_offlinePlayer}
  • {_offlinePlayer}'s location
  • Backward compatibility with existing location logic
  • Online → Offline player conversion

Key Features

These tests are also completely useless since the testing server has no players.

This should also not touch the location expression and instead just register a converter. (Or perhaps create a new expression like last location of to clarify they're not currently anywhere)
