Change godot port to 6005

[idbrii]

Godot changed the LSP port for Godot 4: https://github.com/godotengine/godot/blob/master/modules/gdscript/language_server/gdscript_language_server.h#L47-L48

The change was in this commit:

https://github.com/godotengine/godot/commit/de7873c2d87c3ee8af8c27e35f49767fcc384e75

Godot 3 users can change to use this port in editor -> editor settings -> network -> language server -> remote port. Or they can use let g:lsp_settings.godot = { 'tcp': '127.0.0.1:6008'} to use the old port instead.
