feat!: Add secrets input to workflow call (#79)

This is a breaking change.

You might encounter this error message if you don't change your caller workflows:

```
This job failed
Secret AWS_ROLE_ARN is required, but not provided while calling.
```

In caller workflows, you need to make this change:

```diff
-    uses: oslokommune/reusable-terraform-plan-apply/.github/workflows/reusable-terraform-plan-apply.yml@main
-    secrets: inherit
+    uses: oslokommune/reusable-terraform-plan-apply/.github/workflows/reusable-terraform-plan-apply.yml@main
+    secrets:
+      AGE_PUBLIC_KEY: ${{ secrets.AGE_PUBLIC_KEY }}
+      AGE_SECRET_KEY: ${{ secrets.AGE_SECRET_KEY }}
+      AWS_ROLE_ARN: ${{ secrets.AWS_ROLE_ARN }}
+      GOLDEN_PATH_IAC_PRIVATE_DEPLOY_KEY: ${{ secrets.GOLDEN_PATH_IAC_PRIVATE_DEPLOY_KEY }}
```
