When shell integration is disabled, the env changes are still applied

Testing #182970

I'm guessing that's because applyAtProcessCreation is true by default, but it's a bit surprising when I have explicitly only provided applyAtShellIntegration

collection.replace('FOO', 'REPLACED', { applyAtShellIntegration: true });
collection.append('APPENDING', 'appending', { applyAtShellIntegration: true })
collection.prepend('PREPENDING', 'prepending', { applyAtShellIntegration: true });

it works (does not get applied) if I explicitly also provide applyAtProcessCreation: false, but I wish we could skip that step - related #183831

This was brought up by @karrtikr at #179476 (comment), we'll finalize the exact behavior in the api sync
