fix(desktop): install browser before release smoke tests

[waleedlatif1]

Summary

• Install Playwright Chromium before the desktop release smoke suite. Source-connection E2E launches a separate browser, so a fresh release runner needs the same browser setup as the dedicated desktop E2E workflow.

Type of Change

• Bug fix

Testing

• Reproduced the missing-executable failure with an empty browser cache.
• Ran the added installation command against that cache, then passed all 15 source-connection browser/Electron lifecycle checks.
• Actionlint, lint, all 52 audits, generators, block registry checks, and docs manifest check passed.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Existing E2E coverage passing (workflow-only change)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
