Description

Following the instructions in the Contributor Guidelines I encountered the (common?) issue building mac-screen-capture-permissions. Upgrading it to 2.1.0 silences the message and eliminates a few dependencies.

I see in https://github.com/signalapp/Signal-Desktop/pull/6889 that the issue can be ignored, but wonder if this might be better. I'm new so maybe there's a reason to prefer ignoring the warning to upgrading the dependency.

Fixes #6063
