BruceChen bb18399523 Use dynamic dimension registry lookup in JoinGame and Respawn packets
The JoinGame and Respawn packet handlers for 1.20.6+ used hardcoded
switch expressions to map dimension type VarInt IDs to names:
  0 => overworld, 1 => overworld_caves, 2 => the_end, 3 => the_nether

This only works for vanilla servers with exactly 4 default dimensions.
Modded servers (Forge/Fabric/NeoForge) or servers with custom
datapacks can register additional dimensions with IDs beyond 0-3,
causing the switch to fall through to the default "overworld" for
any non-vanilla dimension. This means players in modded dimensions
would have incorrect world parameters (height, lighting, etc.).

Fix: Replace both hardcoded switch expressions with
World.GetDimensionNameById(), which looks up the VarInt ID in
the dimension ID map populated during the RegistryData phase.

Also fixes two pre-existing issues in the SetDimension dispatch:
- JoinGame (pre-1.20.2 path): The `case < MC_1_20_6_Version` guard
  was technically correct within its enclosing `if` block, but
  changed to `default` for clarity and future-proofing.
- Respawn: The `case <= MC_1_20_6_Version` guard excluded protocol
  versions above 766 (e.g. 1.21 / protocol 767), meaning
  SetDimension was never called for those versions. Changed to
  `default` so all versions >= 1.19 properly update the dimension.
