Enabling SDK extensions doesn't seem to affect PATH

I enable all SDK extensions by defining below env var inside Flatseal.

`FLATPAK_ENABLE_SDK_EXT=*`

If I run vscode from CLI, I can see the `Enabling SDK extension` messages `code.sh` prints. However when I open a new Terminal inside Flatpak, I can't see PATH changes the script does.

I've installed Rust SDK extension and I can only use it if I define the following PATH env var inside Flatseal:

```
PATH=/usr/bin:/app/bin:/usr/lib/sdk/rust-stable/bin
```

I expected vscode to work without explicitly defining PATH.
