Fix Windows release job (#3282)

Summary:
I'm not entirely sure why this broke. Some Powershell versions
support `&&` but others don't. Something downgraded us, apparently.

Failing job: https://github.com/facebook/flipper/runs/4791210127?check_suite_focus=true
Issue: https://github.com/facebook/flipper/issues/3281
Stackoverflow post I copy-pasted from: https://stackoverflow.com/questions/65627536/the-token-is-not-a-valid-statement-separator-in-this-version

Pull Request resolved: https://github.com/facebook/flipper/pull/3282
