[MC-124546] /datapack disable <pack> only works in the overworld

The bug

When disabling a datapack in the nether or the end, the datapack doesn't get disabled. This happens when you either change the execution dimension with execute in ... run datapack disable <pack> to the nether or the end, or if you're are already in one of those dimensions and run datapack disable <pack>

How to reproduce

Open a world (which has the vanilla datapack enabled) and make sure you're in the overworld:
```
/execute in the overworld run teleport @s 0 0 0
```

Run either one of these commands and it will not disable the vanilla datapack:

/execute in the_nether run datapack disable vanilla
/execute in the_end run datapack disable vanilla

Check what datapacks are enabled
```
/datapack list
```
→ as you can see, the vanilla datapack is still enabled

Teleport to the nether or the end

/execute in the_nether run teleport @s 0 0 0
/execute in the_end run teleport @s 0 0 0

Disable the datapack
```
/datapack disable vanilla
```
List all the datapacks
```
/datapack list
```
→ the vanilla datapack is still enabled
