[Windows Server 2022]: Lot of blank lines on running install command with `--unprivileged`.

**Kibana version:**
```
VERSION: 9.3.0-SNAPSHOT
BUILD: 93303
COMMIT: 07655a0a20808401ae4531541ed85885b2f61fea
Artifact: https://snapshots.elastic.co/9.3.0-aa28bea9/downloads/beats/elastic-agent/elastic-agent-9.3.0-SNAPSHOT-windows-x86_64.zip
```

**Preconditions:**
1. 9.3.0-SNAPSHOT Kibana cloud environment should be available.
2. Windows Server 2022 should be available.

**Steps to reproduce:**
1. Install & extract the artifact.
2. Run install command in Powershell with `--unprivileged`.
3. Observe lot of blank lines are displayed in CLI.
- Issue is consistently reproducible at our end.

**Expected behavior:**
Blank lines should not be displayed on running install command with `--unprivileged` on Windows Server 2022.

**What's working fine:**
- The same issue is not observed on Windows Server 2025

Start by reproducing the Elastic Agent install command with --unprivileged in PowerShell on Windows Server 2022 using the linked 9.3.0-SNAPSHOT artifact, then compare the CLI output with Windows Server 2025. Trace the install command's output path and identify where the extra blank lines are emitted; done means the command produces no unintended blank lines on Windows Server 2022.
