Fix: extension pkl reported incorrect imports of repositories

Fixes the following `WARNING`:

```
(10:58:19) WARNING: /home/ubuntu/project/MODULE.bazel:35:20: The module extension pkl defined in @rules_pkl//pkl/extensions:pkl.bzl reported incorrect imports of repositories via use_repo():

Imported, but reported as indirect dependencies by the extension:
    pkl-cli-linux-aarch64, pkl-cli-linux-amd64, pkl-cli-macos-aarch64, pkl-cli-macos-amd64

Fix the use_repo calls by running 'bazel mod tidy'.
```
